Surprising how few people know this trick: Use clear tape over JB weld after applying. It won't sag and can get it thicker. Clear plastic sandwich wrap works, too. I even do it with fiberglass and bondo. Smooth it out.
I'm a hermit and use a million tricks like this but no one knows them. I thought about making a video but it would be an hour long, at least. I never do as it seems to be against my nature.
Second season on the lake, my customer has used it a few times since then. Good enough for for what it is. Either throw the boat away a year ago, or get another year or two out of it. I have replaced engines in boats and the customers let the brand new engines crack the first year.
