I've had LPU paints alligator alkyd (oil) paints. Only a few don't.
404/414 costs maybe $20/qt. Paul , someone who was seriously in business could afford that. "Paul Oman" wrote in message ink.net... Brian - have you tried "old fashion oil based/solvent based" 1 part primers in comparison? Epoxy based primers are becoming more common, but even these old "oil primers' work well under LPU coatings. I'll have to get some 404/414 primer and do some tests too. Can we swop some products? paul progressive epoxy polymers Brian D wrote: You might be right, Paul, but there is a couple of key things about the 404/414 that's important. Whatever kind of epoxy is in it apparently doesn't 'care' (chemically) about what kind of paint you put on top. Plain boat building epoxies that risk amines being on the surface (I forget the proper name for the type ...it includes your no-blush I believe) often prevent alkyd enamels from curing. Regardless of what's in the 404/414, it works and that's the bottom line. At least I haven't discovered a paint that doesn't stick to it well. As the first guy pointed out, it can be confusing if you read the label and assume it's for under the waterline and would waterproof the boat under the paint. The other thing that's nice about the 404/414 is the high bodies and sandability. It has a LOT more stuff in it than other so-called high-body primers and as a result works much better for hiding minor sanding scratches and defects. It sands out nice without requiring you to kill yourself for it. So sure, call it a solvent filled cheap epoxy if you want ...but do you have an even cheaper solvent-filled cheap epoxy-based primer that works as well for primering under most any paint you want AND is high-build and fairs the boat nicely? Suggestions are welcome... I'd be happy to test your product side-by-side with the 404/414 and see if you're right. Brian "Paul Oman" wrote in message ink.net...

The same ingredients are listed, by somewhat more technically specific names, on the interlux web site. -------------------- Yes - so it is just a solvent thinned, pigmented, cheap epoxy........ No doubt everyone pays big $$$ for them to add the solvent into an epoxy.
