Yikes! What a Mess!
Did the epoxy peal off yet, I give that repair about a 3% chance of staying in place for more then 1 season.
Why would you not want to attempt a patch repair like that on the inside first
it would look way better as well as hold better .
Plus, using epoxy on urethane plastic, those 2 materials are totally contrary to each other. they don't even shrink and expand at the same rate! If these parts are made from urethane plastic, why not use a urethane based material for your patch material :/ like urethane rubber maybe?
Has anybody seen the p-tex sticks you use to repair the base of a damaged snow ski?
If you facilitate a big cobbled up repair on the inside and leave the outside flush, you could at least cover the damaged area on the outside with a big sticker :nerd: or maybe some 3M adhesive backed carbon fibre sheeting.
