Hi Ducpainter, i am a car painter by trade. If i do keep it ally finish, i would clearcoat it to stop grease marks etc.
Have you a recomendation for a clear best suited to bare ally?
I use HS Nexa ( PPG) at work.
Cheers.
Your NEXA clear is fine. It's all about the surface treatment.
Aluminum needs an acid etch. There are materials around that won't discolor any level of aluminum finish. There are also materials that will.
I bet NEXA (PPG) has both.
