don't sand it all nice and smooth either, wire brush it or scotch bright pad, (leave it rusty, remove anything loose) clean the painted areas around it and paint it on, that's it, very little prep work.

from what i've been told por was originally invented to coat battery trays, its acid resistant and all that good stuff.
Oh I havent sprayed it yet. Just bought the paint... Your really making me thinking just POR it and never worry again...

My tools are limited to the set I got for auto in Highschool and I got my drivway to work. Id MUCH rather replace it than POR it but thats cash I dont have for sure right now. Im still looking for a decent shop for my LIM that wont rape me on price
