Not sure if this is exactly a detailing question, but I need some advice, guys. I was crawling around under my '07 last night and noticed some surface rust here and there on various bosses, fittings, etc. on the frame - things like shock mounts and other brackets. It's not rotting out by any means, but the history of rusting frames on the Tacoma has me a little uneasy about where this condition may lead if left alone for too long.
I've used rust inhibitors in small bottles (from Turtle Wax if I recall) and that stuff seemed to work great. It mixes with light surface rust and forms a tough coating that arrests the corrosion altogether. Is there an underframe coating of some kind that I can apply to theses areas without making a genuine mess of things in the process?
Any suggestions would be greatly appreciated.
