Re: Is JB Weld a hole filler or a real metal replacement?
I know a lot of the guys swear by JB but I'm not a fan. If I want a true metalized epoxy based adhesive/filler I use Devcon. They make several different products specially formulated for repairs on steel, aluminum and other metals. They have some high temp stuff called 'Liquid Titanium' that I saw used successfully to reattach a broken cast iron flange on a steam boiler. I've used both,the 'Liquid Steel' and 'Liquid Aluminum' with good results. You'll pay a lot more than the hardware store JB but like they say; "You get what you pay for".
