Replaced the polystyrene junk with coroplast and sprayed it black. I also put a black fender stripe on to cover an area of clear coat that was weak/failing. I also put coroplast on the foglight covers. Does anyone have a specific recommendation on what to use to seal the edges and smooth it out? I've heard you can use silicone but I don't have experience with silicone/wouldn't know what kind to use for this.
