Automotive refinish coating gets you on the road
Automotive refinish is not just for hotrods and racing stripes. Refinish paints are applied to vehicles as part of a total refinish, part refinish, or as a touch-up measure. Automotive refinish coating is also an important aspect of the commercial vehicle market, maintaining branding through colour and design across a fleet. Automotive refinish coatings are constantly developing to match the standards being set in the OEM coating market.
In this article we outline the various automotive refinish coating processes and markets including collision repair, car repair paint, and commercial vehicles. We also discuss the automotive refinish companies and suppliers operating in Australia.
The automotive refinish coating process
The OEM coatings that provide initial protection to a brand new vehicle are applied in a many-step process in the manufacturer’s paint shop. A vehicle straight from the lot is coated in five layers of protective and decorative coating: phosphating, electrocoat, primer, base coat, and clear coat. The combined effect of these coatings provides colour as well as protection from corrosion, stone chip damage, and fading. When the coating is damaged, the whole coating system may need replacing with automotive refinish paints.
New looks with a total respray
The total respray market is far smaller than the car repair market, making up about 5% and 95% of the total automotive refinish market, respectively. If a vehicle’s paintwork is damaged, or the choice is made to refinish, have it refinished by a professional. There are many steps involved (some garages claim they use over 100 different steps), and a refinish requires a high level of technical competency. Generally the steps can be divided into two groups as stated below.
- Surface preparation:
First the original car paint must be sanded down, all traces old paint and rust removed. Body damage needs to be repaired in order to ensure a smooth surface, and then the whole surface will need a clinical clean. Finally, masking is applied to areas which need to be protected from the paint.
- Spraying process
Primer needs to be applied first (epoxy, polyester, or urethane based) and then sanded into a smooth and even finish. After this the colour coat is applied, followed by a clear coat. There are coatings available that combine these two layers, such a single-stage urethane. This combines the protective powers and gloss of a clear coat with the colour of a base coat. In a two-stage system, the base coat provides colour and the clear coat is the protective layer which provides sheen, UV resistance, and seals in the basecoat.
Car repair paint for local, minor damage
Not all damage requires an extensive refinish. Small scuffs, scrapes, and scratches can be repaired through the use of car repair paints. These range from tinted waxes and coating pens to touch up kits and 2K fillers. For the best results, a professional application is always advisable.
Accidents happen. In fact, hundreds of motor accidents happen every day in Australia where the annual cost of car crashes is estimated at $27 billion. An important aspect of getting a vehicle back to its best is the refinish. The steps involved in refinishing a damaged vehicle are:
Step 1. – Determining the paint type
The move from solvent-based to water-based coatings over the past decade means that the colour coat (the base coat) in car coatings is now water-based, with the clear coat commonly consisting of solvent-based 2K paints. Older cars may have a range of paints, however, so in order to make sure coats are compatible the shop will test paint types.
Step 2 – Matching the paint colour
Vehicles come in literally thousands of colours, and getting the shade even slightly wrong causes a jarring end product. Specialty equipment and tools provide precise colour readings in order to perfectly colour match.
Step 3 – Replicating the finish
If a vehicle is not being entirely resprayed, it is very important to match not only colour but also finish across the entire paint job. This is not as simple as buffing to the right sheen. When paint is applied it has a finish texture on a scale from “orange peel” to smooth. A refinish needs to match this texture.
Applying automotive refinish to commercial vehicles
A commercial vehicle or fleet has special requirements from an automotive refinish coating. The branding has to be consistent across a fleet, meaning the colour, texture, and gloss need to be the same for each vehicle. Take for example the buses of Greyhound Australia; each bus follows a certain colour code (blue red and white) and represents the logo of the company. Commercial vehicles’ coatings need to be able to endure long hours of damaging debris on the roads, exposure to UV radiation, as well as changeable weather conditions. Because these vehicles are often so much larger, they also need low temperature curing coatings which do not require exposure to heat in a drying room.
A coating failure will lead to vehicle downtime and loss of earnings, so the coating needs to perform and keep the vehicle on the road for as long as possible. Which is why hard-working coatings like epoxies and urethanes are used – they provide superior corrosion protection, durability, and chemical resistance combined with premium quality appearance attributes such as gloss, colour, and smoothness.
