I posted this in another forum last night and should have done it here i think. Im headed out today to get some sealer for the inside of the tank today and was wandering if all brands are the same? Instructions also call for having it pressure checked. Do most shops have the ability to check the pressure or any suggestions? Thanks in advance for any imput. I may just clearcoat it until i can afford to have flatblack scallops on vivid black tank. By the looks of the seam rrattle can will show se
