Ditto what CNKS said. If you want some alternatives, here's some that I am aware of: 1) PPG's OMNI MAE acrylic enamel w/o hardener - recoating questionable/not recommended by PPG 2) DuPont's NASON Fast Dry acrylic enamel - recoatable after 48 hours per the tech sheet 3) DuPont's Centari w/Ultra 1K Pac formulation - recoatable after 4 hours per the tech sheet - probably pricey These three do not require iso-containing additives. There are others, I am sure - especially in PPG's and DuPont's commercial/industrial lines and from other manufacturers, but I am not familiar with them. Color shade reproduction could be questionable in any of the three. Sample test sprayouts recommended with small quantities to determine adequacy. If you are looking for a non-iso, lacquer type of surfacer that is an alternative to the OMNI MP181 that CNKS mentions, look into DuPont's 131S, Fill 'N Sand. If I were you, I'd look seriously into the 2150 dealer paint. I've never used it but it gets mentioned a lot in this forum. I understand it's an acrylic modified alkyd enamel - a hybrid. As such, it's debatably on par with any of the above, except possibly the Centari. You'd want to verify the recoatability though - just in case you need to repair any application errors. Rod
