[DeTomaso] How to best paint my Campys?

[Stephen Nelson]

Just had two sets powdercoated.  Powdercoating folks thought it was amusing
that I asked that they put the rims in their oven as it cooled overnight.
They don't cool their.

So, had them coat them.  They explained that they have to prime them first
or they will see problems like Mike described.  So, they primed then, ($20)
and coated and were fine.  Then I heat treated in my oven downstairs as
described by Mike.  Which, of course, darkened their color a bit.

Hope that helps.

Magnesium doesn't powdercoat well.   It is so porus that tiny pockets of 
gas can form, and create bubbles in the surface finish.   Then it's a 
nightmare to strip them and do it again.

If they are going to be powdercoated, it's best to have the powercoat shop 
place strip them, then place them in the hot oven at the end of the day, 
heat them fully and allow them to cool slowly overnight, prior to actually 
applying the powdercoat finish the next day.   This is actually quite good
for 
the wheels, as it anneals them and removes any brittleness that may have 
developed over 40+ years.

My front wheels came to me powdercoated in the wrong color, but they had 
already been through this process.   I had them painted to match my rear 
wheels, and since the original finish on the rear wheels was thin in places
from 
new (primer showing through), I had the rears painted at the same time....
