Gummi Stone Help

I use a gummi stone to get rid of rust and burrs on my edges and I probably do it way too often, about every time I wax and now I'm noticing that the gummi stone is touching the bases a little bit. After I'm done using the gummi it looks like the outer part of the bases are getting pretty worn (the color is a lot lighter), but after I wax it looks pretty much normal again.

So basically I want to know is it bad to let the gummi stone rub on the ski bases during use?

and or

Is there anything else that I should use just to get rid of any rust off of my edges that won't wear them down or hurt the bases, that I can use every time I wax?
 
having your bases discolor around the edges is from the wax drying out, thats why it goes away after youve waxed. its fine if the stone rubs along the bases, as long as your edges arent below the height of your bases.
 
y do you have rust on your edges every time after you wax? i gummistone my edges maybe 5 times during the life of a ski (120+ days). don't worry about rust so much, it comes off as soon as you ski.

also if you're getting drying by the edges that much, put a few layers of wax on. try 4-5.
 
I guess I don't dry off my skis enough after a at the hill and the edges rust some, and I'm kind of anal about it because I dont want them to rust a shit ton. But I guess I can just ignore it, i didn't know it came off that easily, thanks.
 
not really, although after a loooong time it will start to take its toll on the edges and they will become thinner and more prone to cracking. you shouldnt have to worry about that until they are a few seasons old. also, do you use a guide?
 
There's no reason to use a gummi stone after waxing.

A gummi stone has one purpose:

-de-burring

you can do this after sharpening, after filing down under foot or at the tips and tails. it also can help smooth out a nick in your edge from a rock or something. i'll use it sometimes on a new ski after skiing on it a few times to take down the burr that develops from hitting rails.

It works for taking off rust too, but you shouldn't have rust to begin with.
 
this.

the only time i ever take a file/gummystone to my skis is when i first get them to detune the edges, the start of the season to get rid of burrs from the last season, and whenever i have a edge crack i file that spot down a lot so it doesnt pull out
 
Whats happened here is something that happens to us at ON3P since we use gummis in finishing. The grey 'stone' will wear down from the friction and abrasion, and with enough use, the edge will start carving grooves in the stone. If these get deep enough, the gummi stone can come in contact with the base when you're deburring.

Its a minor scuff. Think of a gummi like sandpaper - so yes, its bad for the base, but its probably like on a whole 12 sqcm of base area, you still have 2-3000 or so square centimeters of good base, so... your call.
