Thread: Fixing holes in Aluminum Boat

You need to remove all of the JB weld before you try to weld it.

I'm going to ask them about that before I buy any. Thanks

I never had a whole lot of luck with that stuff. Maybe if you are already proficient with oxy/acetylene welding, then you could do a pretty good job. I'm not, and just ended up making the hole bigger most of the time.

JMO, the better DIY fix is just a riveted patch with 3M 5200 in between.

If you want to play around with it, harbor freight used to carry a cheaper version. Not sure if they still do.

I would have to agree with Strmwalker here, you could easily end up with a larger hole than when you started. I've restored a couple vintage aluminum boats and have used this.

Just make sure your surface prepped properly and clean as a whistle!

I’d definitely take it to someone that welds AL every day.
It’s tricky, just when you think it’s almost ready. A big hole drops out! LOL

Find a professional welder that has mig or tig welder that knows what they are doing. May cost you a little more but it is better to be safe than sorry.
