Been cleaning up the frame on an old truck, and have the POR15 ordered. They say the metal needs some roughness to adhere well. I am merely knocking the loose rust off with a wire wheel and some 80 grit sandpaper (handsanded). My question is, how rough must the metal be in order for the POR15 to bond? Thanks for any insight.

Por -15 works best on sandblasted metal or rusted surfaces without any scales. The problem is, it doesn't stick very well to painted surfaces.

gloves man gloves and if you can long sleeve shirts that stuff sticks to skin like theres no tommorrow!! I know it took a week for me to get it off my arms when i painted a rear in an old car…

As for your question POR should adhere well to your surface.. as long as it's clean

Thank you much. As far as the gloves, I think I'll get my younger brother to get at the hard parts http://www.chevelles.com/forum/smile.gif

You can use it on smooth metal as long as you etch it first with Metal Ready. You can apply it the way you described, but it will look like a rough surface that was painted over. It all depends on how you want it to look afterwards.
