painting inside frame rail

[ksungela]

The aftermarket chassis for the truck I'm building is getting powedercoated now. I want to coat the inside of the frame rails to prevent rusting. What's your favorite method for getting the paint (epoxy) on the inside of the rails? 2x8 box steel rails with many holes for both access inside the rails and ways for moisture to get in. I'm thinking some kind of spraying wand. Any ideas? Thanks.

Thanks. Do you think I can spray epoxy through it?

I have sprayed epoxy with it. Fine for inside frame rails.

What do you put the epoxy in to spray it through that tube

Also that's a sweet looking frame.

I use a Geo bedliner gun and a schutz bottle. I use the same setup for cavity wax.

What the heck is cavity wax.

Buy it at your jobber - spray can with a straw attached to it ( like WD40) - spays like a liquid but dries into a wax

any other ideas for spraying wands or are the 3M 08851 the only choice? What gun are these used on? I tried searching the Geo bedliner gun but nothing pulls up. Is there a model number ? how do these attach to the gun? I have to epoxy prime the inside of my frame rails soon.

No ONe?

Any schutz gun should work. The wand threads onto the end of the gun. You’ll find schutz and bedliner guns on eBay.

I just use the 3M wax and wands.
