I have started polishing my plenum, again, I have knocked almost everything down with a metal file, and 80 grit sand paper, and plan on going down to 1500 wet sanding, and then polishing it. For those of you that have done it what grit paper did you use before polishing? Should I go down to 2200?
The following works well for me.
Use the BUSCH'S alum. polishing products....When done with the Bushes Alum. polish finish off with Bushes Alum. wax and sealer. I bought these products from the Ecklers catalog.....
And am proof on how well they work, and hold the polished look.
good luck
