Now there is an interesting idea. Im going to contact them tomorrow and find out how/if it works on polycarbonates.
Thanks for the link
I've used this stuff (VHT paint) in the past with good results. The trick is, if you want to call it a trick, is to
paint the inside only. Then be careful with it. Never paint the outside, sand and road debris will scuff it up pretty quick. Use a nice
new 600 grit paper to frost the inside (no going back after this). Old paper may give you an inconsistant pattern (scratches). Clean it good with Windex (no residue). Mask off and spray. A nice effect is achieved if you apply more coats to the bottom end vs. the top to get a gradient look. Clearer at the top, opaque at the bottom. Take your time. If you're really good with the spray can, you can add a little black all the way at the bottom to make it actually black. I haven't done this to my current bike, but am getting ready to do it to a shield I got from Jet to be used on my dad's bike I'm restoring. Mine's got a Cee Bailey's 22.5" and I just can't seem to want to change it. Dad's bike has a full-sized smoked shield I can trade between the bikes when I want to.
P.S. - Our local Advance and AutoZone carries this stuff. I saw matte black engine paint too.
