CHASSIS, SUSPENSION COMPONENTS, AND WHEEL ARCH PROTECTIVE UNDERCOATING TECHNOLOGY

Thorough stripping of old paint coats from bodywork and chassis components of oldtimer cars is key in the vehicle renovation processes.

There are currently several options and technologies available for the removal of old coatings. Here is a summary of the available technologies with their pros and cons:

Sand blasting: this term can be misleading, as it suggests that sand is the only abrasive medium available – but there are other types of abrasive grit in bulk used for blasting, like corundum (aluminium oxide), copper smelting slag, and nut shells. Each abrasive medium has a unique abrasive strength and performance. However, the poor application of these materials can deform the surface. This type of process is most recommended for confined locations with internal bracing, such as the edges of the bodywork. It is not advised to sand blast the panelwork itself, unless using one of the latest synthetic abrasive media, such as plastic grit. Plastic grit, in the form of fine balls, carries a low risk of bodywork damage, while maintaining a very high level of coat stripping performance.
Glass bead peening: a less invasive abrasive blasting medium, which is excellent for stripping coats from small workpieces as well as whole assemblies. Here the abrasive is fine beads of glass, which can be used to gently remove decorative finish coats.
Soda blasting: this is one of the latest abrasive processes, and is growing in popularity. The abrasive is based on baking soda with a specific grain size. While it is very mild to the base material, it has a low efficiency in stripping hard coatings, meaning that reprocessing may be required. One risk of this type of processing is the soda residues left on the base material prior to recoating. It is best to thoroughly wash soda-blasted workpieces before recoating.
Chemical stripping: this is the most complex of all coat stripping processes; however, it is the most efficient and the safest for old components. It involves professional stripping chemicals in tanks, into which the workpieces are dipped. Chemical stripping perfectly cleans workpieces of old coatings and, once the chemicals have been neutralized, leaves the workpiece surfaces perfectly ready for downstream refinishing processes.
Pyrolysis: a process well known in other industries, and involves the stripping of old coats at high temperatures. A vehicle so processed requires the removal of all synthetic and plastic parts, prior to being moved to a pyrolytic stripping oven. Here it is kept at very high temperatures, but under the steel deformation point.
Mechanical or power stripping: this is the most common removal method for old coats. It provides the best control over the stripping process, although it is most time intensive. The coats are removed using power strippers, and abrasive paper and plastic pads.

Temporary protection anti-corrosion primer

The latest generation in bodywork primers for anti-corrosion protection during bodywork repairs after removal of the old coating. The corrosion inhibitors provide at least 6 months of protection after the application.

The water-based resins allow easy fusion or pressure welding of metals primed with the product (72 h after application).

Bodywork Primer is designed to require cleaning only the bodywork locations repaired by fusion/pressure welding after the product application, followed by degreasing twice with SILICONE REMOVER, and the application of EPOXY PRIMER.

PROPERTIES:

Up to 6 months of anti-corrosion protection
Primed workpieces can be pressure or fusion-welded
No sanding to matt required before the application of epoxy primers
No stripping away required before the downstream refinishing steps

Lightweight Multifunctional Body Filler

A multifunctional body filler with carefully selected lightweight fillers and resin that provide great convenience when sculpting bodywork parts. If applied to large work areas in large mixed batches, it is critical to thoroughly mix the polyester resins with the hardener. Otherwise, the decorative paint coat might become discoloured and require refinishing.

Blue Light features the unique Mixing Indicator technology, which shows the polymerisation ratio.

The Mixing Indicator is a visual reference for your assessment of how thoroughly the filler has been mixed with the hardener to avoid component mixing ratio errors. The filler is originally blue, and when mixed with the hardener the colour shifts to grey, and then, when polymerisation ends, the final colour is light beige.

It is natural for polyester fillers to exhibit sedimentation coupled with surfacing of a part of the resin and the dye. It is perfectly normal and common to this type of product. It is always necessary to homogenize the product by stirring it in the container before mixing with the hardener.

PROPERTIES:

Very easy rough and finish processing
Perfect for sculpting shapes on large work areas
The safe Mixing Indicator technology ensures perfect mixing of the components
Creamy texture for easy application
Very low volumetric shrinkage, thanks to spherical fillers

Spray filler

A polyester spray filler with the colour-shift based Mixing Indicator for the polymerisation ratio. The P-S spray filler is a finish filler for the final stage of surface sculpting.

The filler reduces sagging and isolates earlier layers of a filler mixed with the hardener at an incorrect ratio. The special selection of fillers and resins minimises shrinkage to 5%, providing excellent processability on large work areas. Further processing of the product’s layer is recommended after a minimum of 12–16 h at 20°C.

The Mixing Indicator is a visual reference for your assessment of how thoroughly the filler is mixed with the hardener to avoid component mixing ratio errors. The filler is originally sharp blue, then when mixed with the hardener the colour shifts to grey blue and, when polymerisation ends, the final colour is white.

PROPERTIES:

Produces a smooth surface on large work areas
Easy and quick application from a Ø2.5 mm spray gun
Safe to apply in thick layers (up to 300 µm) without sagging

Colour selection

Choosing the correct colours is the most important visual renovation stage. While choosing the colour is discretionary, it largely affects the vehicle value.

This means that colour selection is traditionally limited by the vehicle history, or what the original colour a specific car was manufactured in. These restrictions are predominantly driven by the selling year of a particular model.

Modern environmental protection laws prohibit the use of original materials from the vehicle’s era, while the colour making process relies on formulating a recipe that is as close to the original colour master as possible. The pigmentation capabilities have been greatly improved in recent years, so it is quite possible to reproduce the true colour.

The SPECTRAL Colour System database features thousands of colour tones. The Colour Lab develops more basecoat (thinner-based) and acrylic (2K) recipes from the supplied colour masters.

Water-borne processes are unfit for recoating classic cars, since the resulting coats have weak structures with short life spans.

CHASSIS, SUSPENSION COMPONENTS, AND WHEEL ARCH PROTECTIVE UNDERCOATING TECHNOLOGY

Those car bodies produced in the 1980s and the 1990s require a different renovation process than older vehicles. They are rarely corroded to a point that demands a full bodywork restoration. They most often see the replacement of corroded panel elements; full plating parts, like rocker panels or wheel fenders are replaced with new parts, because they are largely available today.

It is essential to remove old paint coats for a full body refinish. With the coats stripped away, the condition of the sheet steel can be properly assessed while any emerging corrosion can be identified when not visible under the paint coat.

POWER STRIPPING

Power sanding is the best, tested, proven and most popular method of old coating removal. It provides the best control over the stripping process, although it is the most time intensive. Rotary or eccentric sanders are used with coarse grain grit paper or dedicated Nylon pads. In most cases, power stripping is excellent for the removal of incipient corrosion spots. It is good practice to remove old coats in a two-step sanding process: Step one is rough sanding with P60 grit. Step two is finish sanding with P80-P120 grit

ABRASIVE BLASTING

This process is generally recommended for cleaning and stripping:

Engine compartments
Boot compartments
Chassis
All confined surfaces

With good judgement and the right grit material, this process works well for the removal of old coats from the entire bodies of older vehicles. Youngtimer vehicles feature galvanized/zinc-coated panels which are thinner than those from earlier decades, and are easier to deform by abrasive blasting.

HIGH-PRESSURE WATER CLEANING OF COATINGS

This processing method is gaining popularity and preference, first because it entails no risk of panel deformation or overheating when stripping old paint. Water is used in this process, along with corrosion inhibitors which eliminate the risk of accelerated corrosion. The process leaves the surface fully dry, clean and smooth. Smooth steel needs sanding with a rotary or eccentric tool as well as P80-P120 paper to promote good mechanical adhesion of the layers applied in the later steps of the refinishing process.

Anti-corrosion performance: HYBRID EPOXY PRIMER + HYBRID ANTI-CORROSION HARDENER

The HYBRID EPOXY PRIMER with the HYBRID ANTI-CORROSION HARDENER is intended for preservation of metal substrates, on which the combination forms a sealed coating with high anti-corrosive performance.

This primer provides the proper protection of steel surfaces through the galvanic zinc residues left from cleaning with power tools.
