Carbon Fin Glue??
« on: November 14, 2018, 05:01:13 PM »
I've done a ton of research on what glues to use and there are basically 3 different recommendations that they all boil down to. So far I've tried 4 different types of marine glue to keep my pathos pockets rails attached to my subcraft carbon fins. I have even used 6 construction clips - 3 on each side (think giant heavy duty metal clothespins) to help pinch the rails to the blades after glue application. Then get loose in areas or detach completely after every other dive. Can someone point me in the direction of something that actually works? Or am I doing something wrong? I'm guessing I need to go in and scrape out the rails at this point before trying next coat of whatever gets recommended.  :confusion-shrug:

If it were me I’d ask the guy you bought the blades from. 

Personally I would recommend 3M 5200, but I’m sure some little know it all will say I’m wrong.

Believe it or not, there is a secret to gluing the fin.
I bought the Moana fins with pathos from JD, and my buddy also got a pair with same setup from a dive shop.
Mine is still intact without any gap at all after 3 years of diving  :o

My buddy has been popped up a few times. I did call JD and talk to him about it, he said it's in the preparation and then the glue he uses.
I didn't bother to dig deeper since it's a trade secret.

Do you use the clips to pinch the rails onto the fin?

No, I never used clips or clamps. I don’t think it would hurt but the rails should fit tightly. Try to not have air pockets. You can prep the surface of the blade.  Maybe rough it up a little with some abrasive then clean it with alcohol. Maybe a primer prior to glue. Make sure you clean off the excess glue because it looks like shit. The 5200 is white. I used it on some fins about 15 years ago and never had a problem with the rails coming off. They were long bladed Riffe plastic fins so the material is different but it’s all in the prep.

A properly cleaned and prepared surface provides the best adhesion.
