I use G-flex 650 on everything these days and I've had good luck so far. Even built a DIY splitboard that seems to be holding its own...
I can't remember...

I've been using something similar (forget which brand) for a couple years now for all mounts where I'm not concerned about strength (which is most mounts that I do). So far I've had good luck with it - no evidence of cracking or brittleness, no evidence of moisture getting in, and easy to pull the screws out when needed.

The "strength" doesn't come from any glue. It comes from the screws threads contacting the core/laminates. The glue is there for lubricating the screw, then forming a watertight seal around the hole.
In this day and age, imagine if it we actually had to epoxy our screws in in order to make them work?! That would suck.Last edited by DropCliffsNotBombs; 02-04-2012 at 08:24 PM.

A couple guys have done pull out tests for screws with and without epoxy (here's a link to one of those tests). The epoxy adds considerable strength because (as I understand it) the epoxy seeps into the core around the screw. Basically, if an epoxied screw pulls out, it's going to pull a sizable chunk of core with it. Obviously the epoxy isn't necessary to get a mount that's strong enough for the vast majority of situations. Since I'm not a huge guy and I don't tend to rip bindings out of skis, I don't generally bother with the epoxy unless its a mount that I'm worried about for some reason (i.e. reusing old holes where the core doesn't look pristine).

IME you can make new threads in a ski core from slowset epoxy & chopped fibreglass strands, sure someone will tell you the date expired 5min epoxy & steel wool they used while having beers and smoking a fatty didnt work but maybe its cuz he did a shitty job with shitty materials ?
Slowset Epoxy sticks to the screw so you are not just making stronger threads you are sticking that screw to the ski core so if it wasn't you who originally installed A binding you don't know if epoxy or wood glue was used but I would say ANY time you got a screw that won't come try using a soldering iron BEFORE you strip the head

I've seen similar rec'd for high strength mounting of threaded rods in bots - cut a clearance whole larger than thread diameter, fill with epoxy & filler, add threaded rod/screw, let sit.
not that I don't believe ttips, just not sure how much strength would be added from the relatively little epoxy remaining in a good screw.

I take my cue from the abuse of WW kayak's & paddles where you find any resin rich layup is not as strong (why they vacum bag out the extra resin?)so I make sure to add lots of chopped 1/2" long FG filler strand, I make sure to wet out the FG but Ideally I want to end up with more wetted FG filler than epoxy in a damaged screw hole
After a curing time if I can tighten down the screw, if it doesnt spin or pull out the hole is fixed, if the binding is still attached to the ski 5 yrs later it worked and it has for me ... not an engineer but I fix stuff

To resurrect this dead horse of a discussion, are people still using Marine Goop? Now that my tube has run out, I'm wondering if there's a new latest/greatest out there without going back to a 2-part epoxy. I personally find the Goop products to be a complete PITA to work with relative to Titebond III and other wood glues, and also compared with epoxy for that matter. And the Marine Goop starts to set and tack up almost immediately, so I feel like I'm in a race to get everything done, leaving no time to drink my mandatory beer(s) while mounting.
Anyone out there using other 1-part adhesives that are easier to work with and less viscous? Perhaps the GE Silicone II (GE280) Household glue referenced in this thread or something similar?

I used Roo Glue from Tognar (can be procured many other places too). It's a Melamine adhesive. It's worked so far and is "recommended" by Tognar and seems to get positive responses from other folks too.

Yeah I'm familiar with Roo Clear. I'm sure its perfectly fine to use, but their own site does say it should avoid direct water contact. That along with being water based, seems like I might as well just use Titebond III at that point.
Other and older threads have suggested RTV adhesive (silicone) -- I might give the Permatex Clear RTV a shot: https://www.permatex.com/products/ad...esive-sealant/
Not trying to reinvent the wheel here, seems like this would be a viable alternative to Marine Goop without going to either epoxy or water-based.

What's wrong with 2-part marine epoxy? (Titebond at home depot). Paper plate, toothpick, 24hr set time, 4 bucks. Life couldn't get much better.

I've had good luck with Gorilla Glue, been using it for four years now. Has a nice solid "crack" to it when removing screws, but doesn't stick to the screw threads and tear holes in your ski like epoxy can. It absorbs water when curing, and IMHO doesn't overly expand where it's not exposed to moisture in the air, so it only puffs out a little between the topsheet and the binding baseplate.

Wow, didn't realize that it's been half a decade since I started using the GE Silicone glue!
I've been happy with it, and no more rusty screws (which was the norm for mounts with Titebond wood glue).
For mounts where the screw strength might be suspect, I've started using this:
https://www.jamestowndistributors.co...ct.do?pid=8694
[The $19.35 "kit" which actually includes just the epoxy despite the "kit" designation.]
Become my favorite for all sorts of repairs, and on a per-ounce basis actually less expensive that hardware store two-part epoxy.
For binding mounts, on some holes that seemed to be just one more turn away from a spinner, the next day it seemed solid.
Yet still easy to uninstall (i.e., I've never had to use heat, etc.).Mo' skimo here: NE Rando Race Series
