Thread: powdercoating 32 frame , fenderless

oh yeah my car is going all black and polished .. just something about a all black roadster with a big polished supercharged small block ....

You might take a close look at a larger, flat surface to see if
the powder coat quality is right for your taste. Normally, powder
coating cures to something that resembles orange peel. Although
minor, it may not be what you want on your frame. The motorcycle
frame is small, round tubing so it doesnt show the surface
irregularities quite as much.

I have seen fenders and hoods that were powder coated and
then color sanded and buffed. This really looked nice.

The putty that you are referring to is a conductive filler that the powder
coat guys use to fill weld pinholes, etc. You might talk to the
supplier regarding the longevity of the filler in a mildly flexing application
such as a frame....it will probably work since bondo is commonly
used on a wet painted frame for the same purpose.

We have all of our products powder coated. I also powder coat my frames and any parts for my cars. It is the best process I have found, there are many powder coaters out there just pick a good one. a lot of it is in the cleaning process, they can wash it or blast it. I prefer blasting it for cleanliness and adhesion.

AND.....
one of the nice things about powder coat is the toughness.
You dont get swirl marks when you wash or wipe off the
part. Our Jeep has an aluminum body that was coated
almost four years ago and it only shows the most aggressive
scratches (tree branches dont scratch but rocks do). The
frame powder coat is also great. We also had a Land Cruiser
frame powder coated black recently and it looks great...it's a
driver, not a show vehicle.

There are powders intended for outdoor use (UV resistant) and
for indoor use. Your application depends upon how much UV
exposure that your car will get; probably either will work.

For your welds, you might look at some that have been coated
without putty....they dont look that bad if the weld is a clean
one to begin with.
