So I am trying to repair one of my skis that had a core shot next to the edge. I obtained some copolymer and a soldering iron. I cleaned out the gouge so that it was rectangular with a flat bottom of core exposed (about 3mm wide x 8mm long). I further cleaned out the area with denatured alcohol.
Using the soldering iron I melted copolymer string into the gouge. I overfilled it and used the soldering iron to work the material into the gouge and the surrounding area just adjacent to the gouge. I let it cool while initially pressing the copolymer with the face of a metal scraper.
An hour later I went to scrape and the copolymer on the surface seemed like a rubbery plastic that readily released from the ski edge and peeled up from the surrounding base as I scraped.
What was left was that the gouge had a plug of copolymer inside it but it did not look smooth. I have tried to add more copolymer but it just scrapes off. I have tried to add material from a ptex candle and it just scrapes off too.
I am concerned whether the repair will stay put when the ski hits the snow...the fact that the stuff on the surface did not adhere well to the edge or the surrounding base has me a bit concerned.
I have researched forum posts and videos from various sites prior to attempting the repair. Does anyone have any further advice on how to properly apply so this stuff stays put?
Also is it normal for the copolymer to set up like rubberized plastic?
