If you must rattle can use a clear coat over it.

I've heard of hurculiner/linex/rhino liner used on the exterior of bodies on off road vehicles. Not sure I would ever do it.

Sounds like you're trying to paint on a budget... I agree with clear over rattle can if you want super cheap. Not sure how well the rattle can clear will be as opposed to spraying proper automotive clear over the top, but I guess it's worth a try.

Any rattle can will fade and chip in time. A clear coat won't help it unless it's a true polyurethane which the rattle can paint won't like on top of it. Really, it's just as cheap to buy a throw away spray-gun from Harbor Freight, buy a couple quarts of good enamel (not acrylic-enamel) house paint and shoot it. At least you'll be able to color sand and buff (to a point) to make a presentable paint job and still be able to touch it up on the fly. I figure you'd need at least two cases of rattle-can just to get a light coat of coverage...much cheaper to go the other route.

A trick we used to use when I worked for a restoration shop was to use tremclad with a bit of auto paint hardener so it would actually cure. We used this on fuel tanks, suspension and pans. It actaully works pretty good and is very durable. I've shaker canned small pieces with clear and had good success but a body is pretty big and would require a lot of cans. I'd consider a cheap macco paint job. at $4-6 a can spaybombs add up pretty quick.

Samuel, if it is mostly a off road toy, and you are set on spray bombs you could do the inside with rubberized undercoat it covers very well. probably 3 to 4 cans about 4 to 5 bucks a can at wally world, make sure it is the rubberized and not the old tar based, then a simi gloss on outside ( tan, green, or brown ) ,or do a camo design with 2 or 3 colors, would be a good off road look, it would also help hide any body imperfections, just a suggestion, maby maco would do it free if you let them put maco on it.
