All you powdercoaters... a warning.
Powdercoating is THICK. If you're sending a pile of parts out for some nice coating or getting a nice set of wheels refinished, you need to be careful of the various areas that have tight tolerances. For example, a lot of factory wheels (especially late model 911 wheels) have a hubcentric ring that centers the wheel. If this area get powdercoated it will not fit on hubcentric hubs. Seen it happen. Anyway, avoid a hassle, identify areas to not be powdercoated before handing your stuff over. Coating shops won't know what's what. Can you tell I ran into this issue today....

I've had parts for my 'Guzzi coated where it was over 1/16" thick. Use someone who is accustomed to doing automotive parts. Some shops specialize in cabinets and other "production run" type of painting, so the guy applying the paint may not have a good feel for special geometry.
getting it off is a good/bad thing. the stuff is so freaking tenacious, that treatments of Jasco (carefully taped off) had to be repeated several times whilst removing the softened layer with a razor blade. I don't feel brave enough to use a grinder in tight spots and would screw up the otherwise great finish. |
