I had it done on my new frame rails on the Miata. That was over epoxy primer and black frame paint. Good stuff, but our bonehead landscaper for the city blasted the wet leaves and crud off the lawn unto all our cars parked in the lot at work. Then he also left the piles of crap under the cars. I found mulch and leaves and other crud all through my engine bay and windshield plenum. The new waxoil on the rails had a nice layer of grit plastered into it from his lack of consideration.

 

it's 9 out of ten times it's someone else messing up your car

Did you find a decent local place off the website or you knew someone? I don't know crapola about the local places that do it

 

sitting outside in constant cold is less likely to cause rust than bringing a snowy/salty chassis into a warm garage, where oxidization prefers to do it's finest and fastest work.

 

good point - all the more reason to do this I think!

 

John's Autobody and Frame Shop, Dedham, MA. Look for a fame shop and they should be able to do it. He will do the rockers when I scrape together the cash (cough) after my Giulia winter set

 

duhh just found my local ceramic and everything else shop does it - they have a good rep.. cool!
