So... How do your bases look? Is there base burn along the edges? Did you ski abrasive snow? That's what I want to know.
My quick answer is no base burn, the bases look like they always look to me, fine. I put this on my SLrace ski that I use for coaching and get close to 20 days a season on them on hardpack, man made snow. I coach at Ski Bradford in Mass. The skis have been sitting in the basement all summer. I will take a look at them tonight and take (post) a few pictures. The other skis had less days on them, but they all looked fine as well. I read some of your posts on another thread about this. My 2 cents is if I have experienced base burn on my skis, I wasn't aware of it. I might ski 30 times a season. I used 1 pair of skis for a good 20 years and never waxed them. I am probably not sensitive to "base burn", but I still have those skis and the bases look fine. They are clear bases, so I wonder if that doesn't show base burn. I have seen skis with black bases and they have turned grey, whiteish. In the last 6 years I have obtained a ski quiver and I have probably seen that once on a used pair. I wonder if what we see is the black dye in the plastic oxidizing and turning color? To me this is not a serious issue, but I could be very wrong.
I own a boat and I have seen a lot of plastic parts get "chauky" and the surface gets a powder on it and they get brittle. To me, the sun breaks them down and maybe the surface gets oxidized. I don't think that happens to skis (unless you fall a lot on sunny days and expose your bases
) but I could see the snow abrading the bottoms, like sand paper. I expect that wax acts as a lubricant against the snow. I don't think DPS's Phantom adds any lubrication like wax, it just modifies the surface tension and what ever else to reduce friction. Wax will fill in the micro surface voids and add some protection, I doubt Phantom does that. But that doesn't mean is makes your skis slide less well. The info that first came out about DPS and base grinding was misinterpreted. They basically said that Phantom will not change the frequency or need for base grinding skis any more or less than waxing. If wax offers some protection (lubrication) that Phantom does not, it might not be entirely true on the frequency aspect. I also suspect that racing (especially downhill at high speeds) might be much worse for your bases than recreational skiing. So the statement they made is subject to how the skis aare used.
