I beg to differ...he said it been painted recently and thats all the more reason to just get the right moulding set. If you bondo the trim spots up you will wreck the paint job, your rattle can paint won't match and the body filler WILL crack and fall off, you will end up with a shitty looking half assed paint job.
But hey, its your car...go ahead and wreck it if you want, I dont have to look at it!
