hope it works like they say it does, recently put shaved my door handles, still just in primer but looks good
Like who says? The instructions that come with the stuff or the internet drivel?
I would have also welded the hole closed. The problem usually occurs when you park in the sun and the panel heats up and sometimes the repair "ghosts" and you see a halo around the repaired area where the glue is at. You might never see it in a garage and this ghosting is more pronounced with darker colors over it. You'd never see it painted white.
Maybe you'll get lucky. The stuff can be pretty sketchy. Like the bumper repair epoxies. Sometimes it works fine and the next time is like why do I keep doing this. When you do it for a living you step away from stuff that doesn't have repeatability and by the looks of some of the comments in this thread I'm not the only one that's been burned by the better then sliced bread approach some of these epoxy repair materials are marketed under. I've been through many of the training classes/seminars for these products when they are trying to sell a shop on their products. Fusor, 3M, Duramix, Kent and when it comes to the products other then the panel bond there is a lot of adhesion promotor/prep solution/plastic modifier involved. So you need these products to stick the glue to the part. It's bs. The adhesion promoter is what holds the repair material on. In many situations we've gone back to metal welding, plastic welding and other products that have been on the market for quite some time. Any time you mix dissimilar materials you can have unpredictable results. Epoxy to metal, epoxy to plastic. Different expansion and contraction rates come into play. The seam sealers work well but you're not using them to hold something together.
