Well I am doing a little more resto. work than planned with my project . I finished making the rear quaters and started to tack some other parts in. I know I am going to be using POR15 followed by a good coat of Herculiner(interior). Would this enough to seal the seams on the panels or would it be a good idea to just to use seam sealer from CCOT :? Thinking I could also just take the TIG and "drip" seal.
