Re: bras vs clear coat protection
I have bras on both XFs and my A6. Yes, they need to be kept clean and I always wax several times under the bra before re-installing. I also take them off for the winter. Speaking of winter - these are summer drivers that seldom see rain and are garaged, so crap under the bra is at a minimum. In spite of that, there is some wear on the SRT6 where I could not properly fasten the bra one summer. I consider it less noticeable than the dings and paint chips I have seen on other cars. A good shot of Armorall after each washing and bugs come right off with spray water at the next wash.
