First and most important - Excellent DYI section. This idea may have been posted, I've been reading through many pages of ideas... thought I'd share.
I have always been frustrated with the stock "unfinished metal" of all the hex bolts holding on engine / transmission parts, etc... Autozone sells high temp spray paint, bought gloss black, started on one side of my engine. I took off two or three bolts at a time from different components, cleaned off bolts, poked holes in a pizza box and pushed the bolts through so threads were completely protected and bolt heads (with washers) were exposed. Couple fast shots of the high temp gloss black spray paint and I'm happy. $6 bucks. Ever price the chrome bolt sets? Um, yeah - right! I love HD but they have enough of my money. (pic attached)
