Nuke, I thought of the bedliner spray thing for my fender flares (line-x)?

I would like to get the fenders and both bumpers sprayed with the stuff but they are telling me that since they spray it hot, it can possibly melt or warp the plastic fender flares and plastic rear bumper, and that it also might not stick well to it. I think I have seen it done before though.
