Well it is going to look strange with anything grey and blue. But if you do a two tone job, blue on top grey on bottom won't look to bad. I'm going to repaint a bumper here if I get a little time with duplicolor and some clear. My side markers I painted don't look to bad paint wise with this method but I should of sanded them alot better before I painted. Just take your time a couple coats- wetsand - couple more - wetsand - one more - then clear - wetsand - and then more clear and buff. Won't be a high dollar finish but better than the alternative.
