Hey guys, tonight I am finding out that the little red cap on the SprayMax 2k Epoxy Primer cans are removable and have a use. I am not a painter, never knew a painter, nor even aspired to be one. About 6 months ago I sprayed my entire engine bay with 2k epoxy primer and never once activated one of the cans. The internet says to strip it all off and start over because it will never cure. I am also seeing posts on the internet that says if it is dry and scuffs then it's okay. I need the truth. It has been almost 6 months since I've sprayed that primer and tonight I went out to sand a little spot and it seems perfectly dry to me. Any advice you guys may have would be so greatly appreciated. Thank you!
