New to this forum .
I read a lot , learned a lot , and just tried my Eastwood gun .
My goal …. I want to polish aluminium parts , then powerdcoat them to keep the gloss .
I know powerdcoat won t be as shinny as fresh polished alu , but I don t mind , I prefer this than using Autosol once a week on the engine parts ..
So I ordered 2 lbs gloss clear .
Before using it on the real parts made of aluminium , I tried on a steel metal bowl from a fuel pump . thin part 1/16 , so no thermical inertia
Good ground , between 5 and 8 PSI , all is nice .
So I put it in the oven . It s supposed to be 375 deg / 20 minutes .
It seems overheating will turn the coat to yellow . I really want to avoid this .
After just 10 minutes , the powder has turn to a nice gloss .
I turned the oven off .
Is my part ready or must I really keep it for 20 minutes ?
