### ⭐⭐⭐⭐⭐ Review
*by R***G on 16 May 2025*

Needed to do some repair work on our pontoon boat and due to conditions, positioning, etc... TIG was not really feasible (plus I'm just not very good at Aluminum TIG) so I bought a MIG spool gun and ordered this wire to try my hand at Aluminum MIG. I am very pleased with how this decision turned out as Aluminum MIG with the spool gun was a lot easier than I thought it would be. There is still a steep learning curve compared to regular steel MIG but it is still easier than TIG. This wire appears to be good quality and it was reasonably priced. I practiced on some aluminum plates for a couple hours before attempting to work on our boat and had absolutely no issue with this wire. It fed perfectly and welded great! The only point I had any issues was when I moved to a different part of the boat in which the material thickness required a different type of aluminum wire. Fortunately I ordered both the common types so I changed out the roll in my spool gun and had no issues. Even with buying the spool gun and two different rolls of wire, it still saved me a lot of money compared to taking my boat to a welding shop for the repairs!
