spraying por15

[bimmerboy]

i got a sprayer from eastwood for undercoating, with the thought in mind that i could use it to spray por15 and other thicker coatings into cavities and rockers etc. by the looks of it all the passages are very wide and not at all like my paint spray gun, so im thinkin i dont need to thin por15, and since i dont have their solvent(anyone know of a regular solvent that works?) id rather not have to. anyone use this kind of gun for por15?

i'm one of those folks who think POR-15 is oversold. it's good for quick and dirty brushing on without a sprayer. i've used it too.

i've also used a 2-part epoxy sealer and it adheres much better, i think. it's not very thick but i removed the POR-15 from my windshield area so that i could respray with 2-part epoxy.

regardless of what you use, cleanliness is next to godliness. POR-15 will not adhere to rusty metal any better than other coatings. you MUST do your best to prepare the surface. i think for inacessible areas you might want to consider a tar-based coating that stays tacky.

just my opinions

I went to an epoxy manufacturer for boats and he said that most likely it is a one part epoxy. So I would try an epoxy solvent. In terms of places you cant get to I think the problem is that without proper prep the paint will not adhere so well- then you'll just have flaking paint in there helping to trap moisture. I agree that a wax based or tar based spray would be a better idea.

Do not spray POR 15 without professional respiratory equipment and a sealed spray booth, with exhaust. The stuff will get in your lungs and will kill you.

Check back a few pages -- I posted the same warning there.
