Thanks for posting this as it spurred me on to do another once over on my eTitans that haven’t had the glide of all my other skis when on edge. Have used the high degree guide/panzer file method but weren’t perfect and was going to tackle them again this Fall.The panzer is much faster than a Dremel.
Since we drifted to working on the sidewall.
Just went over by them with finer files (free hand-cleaning often), then 180grit sandpaper and finally a Scotch Brite pad. 10 mins of work and now finally the sidewalls are perfectly smooth and catch free.
Now we wait for snow…..
