what do u mean? don't u test your caps? or maybe i just don't understand your post. it looks like your asking us which of your caps will work like we can see what caps you have. theres alot of caps that work with krylon, ny fats and thins gold dots rusto fats....... just go to a website that sells caps they usually list what cans they will work on. and still test the caps to make sure you don't have a bad one especially if your gonna be climbing to a roof.
