In order to fix a deep gouge or core shot, you will need the following supplies:
P-Tex Candle: P-Tex is ultra-high molecular weight polyethylene (in layman’s terms, it’s a kind of plastic). P-Tex is used to make bushings for your car’s suspension, those little things that hold a six pack of cans together, prosthetic joints, and, oh, it’s used in the bases of skis and snowboards. When some of your ski’s base material gets gouged out by a rock, you’ll replace it by dripping P-Tex back in the gouge using a candle – a P-Tex candle, not the kind on your grandma’s dinner table.
P-Tex candles come in different shapes and sizes, but generally you should look for round sticks, the thinner the better. Thinner candles are easier to light and keep lit, which, as you’ll see, is important for making a good repair. I prefer black P-Tex, although it does have some disadvantages compared to colored P-Tex, which I’ll mention below. I also generally go to a trusted local shop and buy my P-Tex candles from the tech, as it usually isn’t available in the front of the shop. Unfortunately, it is difficult, if not impossible, to tell whether the P-Tex you have will be good or bad without actually using it. So my advice is to acquire and test different kinds.
Fire Source: Use a lighter. Matches are very difficult to work with.
Scraping Device: I use a retractable razor blade. If you use this tool, however, it is important that it not be razor sharp (the one I use is actually extremely dull). If the blade is too sharp, it will be very easy to gouge large chunks of previously undamaged base. You can also use a metal scraper.
Base Cleaner (optional): You can get this at most shops. It will help you clean the area before melting the P-Tex and dripping it into the damaged base area. It is not essential, but it will help your fix stay put. A solution of 50% water and 50% Isopropyl Alcohol (rubbing alcohol) bought from your local pharmacy also does the trick.
