Hello all....so as a few of you are aware I have been stumbling all over myself during my first resto. My latest issue was not removing all of the factory finish off of the cook box prior to painting. My result was a blotchy look...it was textured where the oem finish remained and shiny where my wire wheel took the box down to bare aluminum. Well u guys have me talked into stripping off my high heat and taking the ole gal down to bare metal to save this project. It is rec to use the Harbor Fright brush cup. I have a bin in my shop with several other brush cups which brings me to question number 1.
1. Does it matter how coarse of a brush cup that I use? I think the more coarse cup leaves deep scratch marks so it appears the mid range cup is best right?
2. When using the cup and a drill what is your technique? I was laying the cup at an angle and doing a push pull never using the cup flush because it will just act erratically. So I guess I had the cup at about a 25 to 35 degree angle of attack....is that what u guys do?
3. After removing the oem finish and revealing the aluminum do you do anything to remove the brush cup scratches? A soft cup would prob not leave scratches but a med or coarse certainly does. I feel if I paint over the scratches I will have screwed up again.
4. Last question......my cook box has warts! yep.....it has bumps in the aluminum in a few areas. Should I just take the grinder to those bumps to smooth them out or is there a better way?
Thanks
