Also...if that doesn't make 100% sense to you or your uncomfortable doing it on your own...TAKE THEM TO A SHOP...don't ruin your skis even more/hurt yourself.
you dont want it to drip on the gashes, that wont fill the cut. you want to rub it untill it starts to get gummy then remove it from the base and let the candle get warm again and repeat.
good luck if you use a plastic scraper, you want a metal one it takes it off much easier and doesnt ruin your base.
