3rd day on my brand new AK JJ's, I made a bad call and took a sketchy line off a cliff and hit a rock.

I've done plenty of smaller ptex jobs on my skis but I'm not sure of the best way to go about this this due to its massive size. Any experienced ski techs out there that can give me pointers on how to get the best adherence. Help much appreciated.

layer your ptex, put down 1 layer, let it dry, then cut it slightly with a razor blade zo the next layer can "grip" into the previous, then proceed doing so till it's completely filled up ...

however for a repair like this i'd consider taking it into a shop, they can repair it quite easy with a ptex and it'll be much stronger and better than the average homemade ptex dripcandle repair ....

I'd give Ptex one day, then it'll come off. You need to have a shop base weld a new section of base in there.

So, 1cm wide, 7cm long shot from yesterday.
My Coreupt skis have extremly thin plastic base. Although the wood is not visible yet, its a shitty shot.

PTEX and its good to go?

100% epoxy on something that big (buy some good 24 hour stuff). Don't even bother with a layer of ptex on top.

edgegrip is your best bet. Got a 2 inch wide by 7 inch long coreshot and he said ptex is a shitty material to put in bigger coreshots. use edgegrip, which apparently only shops have(?)

now that i work in a shop, i would retract my previous comment (from a year ago)
it's gonna rip out anyways, you need a shop to baseweld it back together and even then it might still come out ....

This, except I like to heat up the edges of the base where you're putting the base weld in.  It helps the new stuff to adhere to the old stuff if you heat it up unti it starts to look wet first. 

But yeah, I'd have a shop fill that.  Basewlelders do a much better job than candles but at least it's not on teh edge.
