painting hidden areas

[jackfrost]

so I'm spraying epoxy on my body shell after it was media blasting, and I'm finding areas that I can't get the spray to, like behind the quarters, inside door pillars and inside the rockers. I don't think these areas were necessarily blasted, but I'm also pretty sure there's no longer any original rustproofing left. is there any sort of gun attachment wand or something that will let me get epoxy into these closed spaces, like the rockers?

Eastwood has some undercoating guns, would these be able to handle normal primer like epoxy? is there a better/cheaper option?

Im not sure I would try to use epoxy primer in those areas. The areas sound as if they are not clean enough for the primer to stick anyway. You need the metal to be clean and free of contaminants, and if you cant reach them, Im not sure the primer is going to bond well enough to protect the metal.

I would get some underdcoating and hit those areas. The undercoating will stick to just about anything and will do a good job of keeping the moisture away from the metal.

Keep in mind Im not a body expert, this is only an opinion.

I'm not sure how your car is set up but my 65 GTO has removable plugs at the inner front or the rear wheel well and also at the front of the body, behind the fenders. This gives access to the inner rocker. I spent an hour or two with with an air gun and a garden hose cleaning out the inner rocker until clean water came out. I have a undercoating gun with a two foot flexible hose and nozzle attatchment and plan on spraying in a generous amount of POR 15. I figure this can't really hurt and the POR-15 won't retain moisture like some rubberized undercoaings might.

Just my two cents

that's probably what I'll go with. I just didn't know if you could spray regular paint through and undercoating gun. turns out they have paint exactly for this purpose. who woulda thunk? :razz:
