hi mate, the wear and tear should be good providing you use the right clearcoat, ie the 2k laquer i sell on my site or another i can get my hands on called clear 4 chrome, either of these will sufficiently protect the surface from stone chips etc. its relatively easy to use, its pretty much the same as normal spray paint but you need to use more of a sweeping/dusting motion when applying. the only thing i would say is that the surface you are applying it to has to be smooth as a babys bottom, because the chrome will show up any blemishes.
