After the summer the skies are still covered with wax .If i want to touch the edges with the the tool shall i scrape off the summer wax and touch the ski edges and then i wax again.
Any suggestions ?
Yes. Always scrape the ski well prior to any tuning as the base needs to be clean and flat as it is before you use any tuning tools.
I hope by now you figured out you screwed up when you put the skis away.
You tune before you wax.
Just scrape them and ski a few runs, it's early season, either way, the wax will ski off in a few runs. Then do a good tune that night.
FWIW, I taken to using my Dominator Hyperzoom as my summer wax. That way I have a good wax for the early season temps. Don't use the yellow much anymore. If it's going to be warm in April I'll put some on.
