High Build Primer

When last painting the epoxy primer on the shell, I rushed the job so there were quite a lot of runs and bad orange peel. I had to re-sand the entire shell inside and out to remove the runs and orange peel which did expose a lot of bare metal areas.

This re-sand work included detailing the engine bay and front apron.

I masked off the underbody to prevent any overspray getting on the underbody coating then I got two good even coats of epoxy primer with the paint gun adjusted properly.

The next stage of painting requires the correct PPE as the high build primer contains isocyanates (classified as a carcinogen). I purchased a full-face respirator with chemical vapour filters to prevent any absorption via skin or eyes, and was used with the full coveralls and gloves I've used previously.

My paint shop advised that a white primer would be required to yield a bright finish with the final paint colour. The white primer has the benefit of showing if I sand through the high build primer and into the grey epoxy primer underneath, and stop sanding at that point so as not to expose any bare metal. To prep for the high build primer the epoxy primer was first sanded with ~180grit hand pads, then two coats of the white high build primer was applied.

For the interior, only the areas that will be visible after carpet, dash, seats, trims etc installed was painted in high-build primer. 

The same process was completed for the doors, bonnet, bootlid - sand epoxy primer with 180grit, paint multiple coats of high build primer. Then the same again for the other side of these panels.
