I have the chin spoiler and my bf has the roush stage 3 bumper and we've never scraped. I just had my bumper repainted since it looked like crap...My chin spoiler was scraped some though from a tow truck guy (he was stupid)...I sanded it down on the bottom edge and repainted it with black trim paint lightly. Looks brand new now I do like the chin spoiler look (painted or not)...after i had the bumper painted and the chin spoiler off still...looked ugly! haha....
