Unfortunately, there is no magic cure-all for this problem. The only solutions are to install a bra, install the clear film (clear bra), or keep doing what you're currently doing. I have never liked bras. If they don't fit perfectly tight, they can rub on your paint and actually wear through it. Sand can get wedged under the bra and scratch the paint too. Then there's having to take it off and put it back on every time your detail the vehicle, which is a pain in the butt. With my last vehicle I had a clear bra installed. At first I liked it, but as it aged it yellowed and cracked and eventually it looked terrible. All I do now is apply several coats of 845 to the front of the vehicle. The bugs are still a pain to clean off, but at least they're not staining the paint this way...
