I had 19 pre 71 Maserati, deTomaso and Lamborghini rims stripped,
prepped, cleaned and powder coated in 2007. Only one had a problem, I
dropped a wrench on an Espada rim while rim was laying on floor. It
created a small chip which I filled in with silver color WURTH rim
paint and a pinpoint brush. No other issues have shown up. The Bora
and Ghibli rims were done normal thickness while the Espada and
Mangusta rims were done thin coat, {3 mills ? or so } because it was
important that the original rough cast marks and line creases and
workers marks still be able to be seen. So the original imperfections
are there yet strongly protected with powder coat.
My mechanics and I cleaned all rims with a combination of Aircraft
Paint Stripper, scrub brushes, 4,000 psi pressure washer with a
rotating 0 deg nozzle, Foamy Gunk and baking soda to neutralize. Sand,
walnut shells, glass and soda blasting was NEVER considered as that
process will or could, not known to me and not willing to risk, damage
and change the grain structure and face pattern of the rims.
We took great care not to damage any of the original Zinc Chromate and
if we did then we brush painted more Zinc Chromate over that area.
Then had the powder coat man to heat up the rims and do his job
quickly and let the rims cool down overnight in his oven. I believed
that heating up quickly which was only getting somewhat hotter, though
close to the same heat ramp up time as hard core racing and having the
brakes heat the rims.
So I was just using basic liquid cleaners sweat, pressure washer
and a hard heat up though slow cool down to cure the paint. They are
beautiful and dependable.
Some basic info.
