ive been testing the water with plasti dip and similar products on my 1/10 scale rc bodies.
plasti dip is the best so far. the more coats, the longer it lasts.
don't expect it to stay on if you are actually wheeling your rig. if it gets damaged, tape it off and just reapply. no big deal. if you don't want to peel it off, plasti dip sells a product you spray on and it turns the dip back into liquid and you can just pressure wash it off. simple.
dupli color's version is absolute crap. zero coverage. i used 11 coats and i could see through the product.
rustoleum is supposed to be good but i find it needs more coats to get the same coverage as plasti dip.
all my own experience but hey, id say get a small project piece, try it out and see if you like it. if not it comes off. just remember the MOST IMPORTANT THING. LAY IT ON WITH MANY LAYERS. if its too thin, it will be a witch to remove. if you put 4 to 6 moderate layers it should peel right off.
