Does anybody know a source for light colored 2-part polyester putty? The ones up here all have a bright colored hardener which helps on the mixing but shows through after a thin coat of white paint. I'd like something in a light grey or white color (after mixing) and preferably in a small quantity..
Thanks

Roy - try 'UPOL Dolphin One Fill UPO660'. It is a white 'All in One Premium Body Filler' (TiO2 pigmented) which comes with a white hardener paste - doesn't get more white than that. It says it won't clog sand paper and is resistant against pin-holes.
