GFlex is the bomb, I once fixed a 550 engine mount with it. The rubber and base separated I sanded it with 36grit and cleaned with acetone, then applied GFlex and clamped in vice. Lasted a full summer like that. You can also get the west systems aluminum etch kit which works really well with the GFlex.

Yes.And l guess you could say that.

JD,l have seen that 3M 4000 before but never have used it.Have you used it for a while and had good luck with it. lm always open to trying different bonding agents.l use the gflex on my hull inserts too and have not had a failure yet.

Yes, I used it on all my builds and it been holding up well for 6+ years or more. Used it for all thru hull interfaces.
