It was an election year, they elected to not use enough bonding agent.
Yeah it is. Got any tips?
I'd start by asking L Stone what they recommend. More than likely you'll be cleaning/scuffing/prepping the best you can and using epoxy to fill the void, clamping and curing. If delam is completely thru hull to interior don't forget to back/seal the inside or you'll wondering where all your epoxy went.
I tried emailing him, but I got no response so I decided to post it here to see if anyone else could help.
Did that delam track , as in spread further on the inside? Is bond line exposed inside ? What's the construction, carbon bottom/glass on top, vice versa?
Hit him up on FB.
Yes if I look through the crack I can see fibers against the walls. I don’t believe the bond line is exposed but I can check again once I get home. It is carbon bottom and fiber top.
What brand/type of epoxy would you recommend.
Exactly what I'd do. I'd use a slow epoxy , my weapon of choice would be US Composites 3:1. Flip the boat upside down and using a slow epoxy and time will allow it to permeate/ propagate fully into the void. Be sure to check that the void is sealed on the back side so the epoxy doesn't run thru. And cleanliness/scuffing/prep is critical, you'll only get one chance to get it right. Grinding it out for a second try would be a pia.
That's definitely a consideration , why I asked about materials of construction and did it track in previous post . If those bonding binders can be "thinned" with heat that would be a +1 for binder. Maybe a better choice if you can flex the delam open/close and the separation doesn't look like it tracked, sort of using a pumping action to fill the void. It gonna be a judgement call based on what you see.
The hull I fixed had a wide bond flange. So I was able to get mixing nozzle in there and make sure I filled it all the way. I actually too a drill bit and drilled the ends of the crack. In an effort to keep it from spreading. Similar to what you would do if you were welding a crack in metal.
Lol. Here's a motor mount repair in a Phantom. US Composites 3:1 and adding West 404 for bonding. What's nice is you can add 404 for a putty or a pour consistency. And lol again, I covered it all with 3:1 and graphite as a dye.
What is the best way to make sure I properly clean/scuff/prep it correctly and what exactly would I use. I’m new to this and it sounds very critical that I don’t mess any of this up.
