painting question
Go with a standard paint gun set up. around here the standard prices are 54/gal for paint, clearcoat is 40/gal not sure what the thinner/reducer is a gal.
For the future, talk with the painter about adding a bit more flex additive to the basecoat and that might reduce the amount of rock chips. They willl have to put some in anyway (for the plastic and fiberglass) so, if they add, maybe 5% more, it will reduce the risk of getting anymore chips.
