I just bought a older aluminum jon boat that has a couple of dents in the bottom of it. I was wondering if anyone knew if they could be pounded out? If so, is there a special procedure for doing this or do you just grab a hammer and go to town.

Dutch Peter Senior Member

Both approaches can be used, it depends on the depth and sharpness of the dent, the thickness of the material, spacing between the stiffeners.

Wynand N Retired Steelboatbuilder

Just remember the "dolly" as well when you off to town with the hammer.

Last inch across proved his abilities. Pointy or sharpedged dent- cut out, patch, sand smooth. Thickness made no difference to him.
