I have that spots under the sealant in the fender wells. Plan to buy some 0.025 wire. Brush on POR15 and use some type of seam sealer on top of the POR15. What type of seam sealer should I get? Something that will work with the factory sealant that already exists. And well a sealer stick to the POR15? Newb questions I know. First time doing this though. Thanx in Advanced. I there will b some haters that will say use the search button..
