In short, I wouldnt advise you use this!!! A while back you might have seen my newly painted valve cover
from:
To:
now between the silver and the blue, I used the 500 degree clear... mainly to protect the silver when I was going to tape it off..... side note, the silver was close to a chrome, like my heat shield, but as you add clear, it dulled it to the "grey" you see in the picture....
A week later, the clear started to turn to yellow, now it's embarassing to even show... So if you value a piece, and dont want to rip it out to redo it (unless you're going for yeloow....or sumtn) Dont Use Clear!
In conclusion... I grabbed my valve cover that came out of my car (yes I was lucky enough to have 2), and poilished it... first I removed the 3 bars (that are painted blue in the pic) with a grinder, then smoothed everything down with a my other die grinder, but that left ugly swirls... so I started with 220 grit to rid of the swirls, then 400, 800, and wet sand with 1000, used a rouge compound and a buffing wheel, and topped it off with some polish... came out pretty good... pics suck, but the final product is nice... whatcha think?
