Hello


I got a red (hard) swix gummy stone and it is not very effective at removing rust from the edges.

Should I bump up to a blue (extra hard) or move to a diamond stone? If a diamond stone what grit? The universal one?

Nope, the softer the better. If your gummi is having difficulty, how much rust do you have on there?

You may be better off starting with a scotchbrite and some windex.

The rust doens't seem that bad, however I am new at this. I didn't have a green scotchbrite however I had a blue sponge with the blue pad (not as abrasive) and I sprayed some silicone spray ( didn't have and WD-40) on the pad and rub down the edges pretty aggressively. Then I took the red gummy stone to them. They are kids beater skis 120 Rossi Bandit Freeride that I think I am going to flip on craigslist.

I disagree, use a Blue Hard Gummi. Red is too soft. And an additional down side is the softer the gummi the more gummi material inadvertently hangs over the edge and can dull your edge. I only use blue.....period!

I just noticed that you recommended windex, for some strange reason when I went to the garage I thought you recommended WD-40, hence the reason I used silicone spray,

220 grit wet sandpaper. Wrap around a diamond stone or something like that and go to town wet. Easy.

the 220 wet sandpaper worked great... I got a sheet and cut out a small piece and wrapped it around the gummy stone..

Tried the Windex and scotchbrite pad last night on a friend's old skis what a difference it made. Thanks for the tip. I was surprised at how well they cleaned up. Greatly reduced my gummi stone time.

Now if you go to tune a ski that is super burred, just do the same before filing. Your file will thank you! Also good to soften a machine heated edge prior to filing.

Here I go in the worlds longest tuning video. Here is the part for viewing pleasure of any wondering.
