I never once told him how to do it. I just stated what I did.
No I have not refomed a ski. I have seen all you crazy f'er do it, and it looks like it sucks, but sometimes must be done.
When I put in my foot wells, my foam was already wet. Not soaking, but pretty damp. So I know my ski already needs to be done.
I also think the silicone will keep it sealed. I didn't cut away any turf, just pre drilled and went right over the turf and foam. I squirted silicone with a caulking gun into the holes, and then screwed in. I personally think it sealed just fine.
