Make sure you ask for the Mar-Gaurd, It has a scratch resistant coating and It should have the UV coating on one side also. I saw some 1/8th inch thick stuff at home depot, but it only had the uv and no scratch resistant. A 4 X 8 foot sheet usually runs around $200 (with Mar-gaurd), and I can almost get a full car done with it. If you can't find any at the glass shop, a race car fab shop could probably make you an exact fit.
