I had the wheel well patches "glued" on my 77 Silverado 2 years ago. Well now the 3M adhiesive is started to break down and you can see the boxside coming off. Even worse is now water has gotten behind the panel and is now bubling pretty bad in two spots. Not making that mistake twice. This time cut the crappy metal out and weld in good metal. I dont trust gluing metal to metal one bit anymore. It was all done properly with no residue just isnt as good as welding in my opinion
