It’s complicated by the fact that half of it is under that trim piece. The end game is to buy a new pre facelift trunk anyway, which I’ve already tried and failed at (got burned on an even rustier one).
I just need a good band aid fix for now until I can bring myself to spend 500+ for a new trunk (and thats before a respray). I already did a little touch up job on a smaller bubble but it wasn’t pretty so maybe I just nees tips re: how to feather and get a smoother finish. The touch up kit I have includes paint, primer, and clear.
