I'm with attison. I want my name on as few lists as possible. I do however believe in their cause. I just can't help but think, if I wanted a list of firearm owners with addresses and phone numbers...id probably contact the NRA. Just sayin...
I work at Sherwin Williams. Use a good masonary primer (block filler) and an elastomeric coating and you will be fine. If elastomeric is too expensive a good quality exterior paint should hold up. Come to Duron in snellville, ask for Zach and ill hook you up. Good luck
