decals vary as the clearcoats, most clearcoats that are applied at the factory have alot more flex as well as it's more scratch,chip resistant than most clears on the market,the reason is ,most paint shops never bother to mix in flex agent into the clear,any who, I just figured I'd throw in my 02. cents,
as I said before, I'd never do it on my car or any of my customer's cars for a simple fact,that there is a chance of splitting,cracking issues over the years, though I guarantee my work as long as you own your car, I do not want to take that chance and fix a problem that could have been avoided by simply using the same stripes/billboards/decals you were planning on applying before the clearcoat or even after the paint job is completed, if you'd like me to explain that process, just ask
