The new Tab Magic Molding Putty from Polyvance is a two-part moldable, flexible silicone rubber that is non-toxic and temperature resistant. Mix equal parts until a uniform green color is achieved, then quickly press onto the headlight tab where it needs to be welded. The rubber will cure in about 15 minutes and tightly support the fine details on the top of the headlight tab while you weld the backside with your Polyvance nitrogen plastic welder. When finished, peel off the flexible Tab Magic putty to reveal a nearly finished tab that should just need minor work to finish. Although Tab Magic Molding Putty is not remoldable, it is reusable on the same type of headlight tab.
