LINE-X Xtra is a product that's made by Dupont only for LINE-X. Xtra prevents fading and loss of gloss and is fortified with Dupont Kevlar for extreme durability. If you get Xtra for color matching, it will contain all the pigments and metallic flakes like your Hummer's paint. If you haven't seen Xtra, you should, it's really nice looking.
When talking do-it-yourself products vs. professional products, your not talking apples to apples. Professional products are WAY more durable and in most cases, look a lot nicer.
H2 stuff: Two-tone Xtra on a H2 plate (No fading, no loss of gloss, no rock chips).
This H1 had a DIY product in it. We had to strip it out an then apply black LINE-X Xtra.
