A few years ago when we talked about it last I took knucks recommendations and purchased some car maintenance products. I used them on the old car, but never on the truck. Knuck, you would be proud of me, as over the last two days I got rid of the baked on bugs, washed and clay bared the entire truck and finished her off with optiseal. Now a final question for you, what is the best thing to use on chrome pieces?
