I'll try that for the next round. Of course, my truck's a working-class sort of guy, and anything that shows off the dings and imperfections may be counter-productive. I've enclosed an attachment to show what we had to start with...

But that's a great finish you've worked up. If I can't find a flagged brush, would foam work tolerably? Or should I go with a high-end brush?

Second question for the room...has anyone tried this on the inside of their vehicle?
