Do you or does anybody know if there is any type of compound that's safe on paint that I can put to fill in the slight gaps in the edging around the back? I know it's different for everybody.. but i'm finding that almost everyone has some sort of gapping with the OEM mud flaps and was wondering if there is a way to fill that with some sort of black compound to make it look cleaner and also to make it not get misc. debris inside..It's been a habit of mine for years to add the OEM splash guards to protect the paint. Driving in winter in the snow taught me that. I don't mind the look, barely notice them after a bit.
