Unfortunately i didn't have a file or a grinder. Quiksteel cost me 3 bucks and the u bolt cost me 1.25 I got them both at home depot. I had a square piece of steel lying around. No shipping no waiting. Except the 15 minutes it took for the epoxy to set. Epoxies today are not the same as they were a few years ago.
QuikSteel is an all-purpose, full-strength adhesive that bonds like epoxy and hardens like steel hard in 15 minutes - full cure in 1 hour.
QuikSteel seals where other products can not - under and in water, in chemicals, and even in a liquid while a leak is occurring. It is safe, fast, long lasting, chemical and heat resistant.
QuikSteel can rebuild, reshape and repair almost any surface in your house and car, including all metal, wood, glass, ceramic, fiberglass, most plastics and masonry - even concrete. In fact, we can't think of a surface that QuikSteel won't work on. One square inch of QuikSteel can lift three cars. 500º temperature resistant Bond holds to -90º F
