I never claimed that it lasted forever of that it did mantane the warrenty but the fact is it works and is cheaper. Second dupont pay for you to push their product they will never say another product works. Its not just Dupont but all the big guys that say you can't mix reducers, additives, clears, primers, prep agents, sealers, hell I have even read data sheets that say you can't use a differnt brand of flake.
I am not saying your wrong. But the cost of paint is not 300 not even using all dupont products.
