Powder coat chassis: cleaning, preparation and painting
This is a typical example of a car chassis blasted and powder coated. We have powder coated chassis for vintage cars, Triumph Stags, Kit cars, kart chassis, buggy chassis and formula 3 racing cars.
How to prepare your chassis for painting
All we need is what you want painting.
- The chassis or sub frame needs to be striped of all brackets and fittings.
- Remove bearings.
- Remove grease and road dirt.
What we will do:
Cleaning and preparation
The chassis will be placed in or controlled pyrolysis oven where it will be heated to 440 degrees Celsius. This will burn off the grease and old paint, road oils and grease and turn it to ash. The heat and weight is distributed evenly to prevent distortion. The heating process will also semi anneal the steel to extend it’s life from fatigue fractures. The chassis will then be grit blasted to remove rust any residual paint ash and give the chassis a good key for its pre-treatment.
The Tri-Resin™(steel) powder coating system is then applied. The same high specification paint system that is applied to our architectural commercial work.
- Liquid chemically pre-treat steel, and seal with an acrylic resin, for corrosion protection.
- To epoxy powder coat prime, for a waterproof film and a thicker aesthetic finish.
- To apply highest quality architectural grade polyester powder, for better ultra violet protection compared to industrial polyesters.
- Average thickness 140 to 200 microns. (Industry standard BS6497 only requires one coat at 60 microns.)
You have two choices:
- Leave in the nuts and bolts, these will then get painted. The paint around the edges of the threads will be broken when they are removed, leaving a serrated edge but the threads will have been protected.
- Leave the threads alone, and we will mask them with our assortment of silicone bungs, but be prepared to occasionally run the thread with a tap or dye.
We will endeavour to protect as many threads as possible
Most jobs are turned round in around two weeks.
Many first time customers have the chassis painted and come back a few weeks later with extra components "wish bones" and other suspension parts. Consider bringing other parts as well to save time. If the chassis and suspension is all painted you can start reassembling as soon as you get them home.
The price to powder coat a similar chassis to the one shown, approx 4m long, in black: From £280+VAT.
Other colours are available, approximately 100 to choose from - please allow an extra £25.
Frames will need to be delivered to and collected from us.
