Remember I don't have a spray gun at home and away to mix epoxy two part. I have to buy the $21 to $28 rattle can two-part epoxy to give it a quick cover up to buy time... If I have the whole thing blasted to metal I would have to take it to somebody and just have it epoxy coated... This way I can buy two three cans and get it the spots covered and have it ready for paint..
