Repair of gouges in your base is a fairly easy task for the mechanically inclined if you follow the steps below:
Minor lengthwise gouges under foot will not affect performance. Gouges across the base or any gouge in the extremities require repair.
Preparing Repair Area
Clean with base cleaner and trim ragged edges with a sharp blade.
Sprinkle Toko Repair Powder in gouge, cover with Mylar and melt with iron to bond repair material into gouge. Some choose to light p-tex candle and flow melted material into gouge, but the repair doesn't wear as well. The preferred method for deeper repairs is to melt p-tex wire with a chisel tip soldering iron available at hardware or hobby stores.
Repairs along the edge or where the ski core is exposed require Metal Grip. Metal Grip is a combination of polyethylene and epoxy. The epoxy bonds to the edge or core material for a lasting repair. Use a soldering iron with a chisel tip to melt Metal Grip. Finish filling repair by melting p-tex wire over Metal Grip.
