Will it stick to a polished frame very well?

Will it offer much protection?

Will it yellow?

I've done it with a polished manifold before. Danny sold the car so I dunno how long it lasted - but it looked good!

Danny has a pic somewhere...

I have seen CR480R swing arms clear powder coated and they look good and still looked good several years of racing later. When I asked about this I was told getting the swing arm absolutely clean and free of any grease (etc.) was critical to the initial result. See no reason why the clear coat would stick to a polished surface.

This is just theorizing but I don't think a clear powder would hold up the abuse. When you polish the frame you remove the irregular surfaces, ridges, fissures and such that powder coat would use to hold onto. From past experience(8 years ago) it will yellow from the sun and abrasion. Can't give a better answer though, haven't kept up on advances in the chemicals. All I know is if you want the shine, gota put in the time.

or have the frame chromed......then the power washer blows the shit right off.

the local chrome shop does stuff in-house. everywhere you want smooth & shiny has to be polished. everywhere that doesnt matter must still be clean. but if you take the pieces in ready to throw in the tanks, its MUCH cheaper.

The best surface prep for powder coating is media blasting followed by
chemical etching. This combination provides a clean roughened
substrate for the powder to flow out and adhere to. A highly polished
surface is probably the least likely to retain the powder.

Clear powders are not as durable as pigmented and will not tolerate
chemicals (like gasoline). I wouldn't recommend using clear powder
on anything that will be ridden.

dogger

hmm being i work in a PC shop now you could have the frame SUPER CHROMED then CLEAR over that (after the frame was blasted lightly to give the PC something to hold onto) the SUPER CHROME does look pretty sweet if done correctly....(cant go heavy or it looks GRAY)
they make rubberized coatings also that are prob. a bit tougher. ill tell ya in a couple days since we are gonna shot a go cart frame tomorrow...
