Snowshoe - If you are going to entirely resurface your ski base with a Ptex candle, you are in for a long, long job.
I have used P-tex over the years for mostly gouges digs and scrapes, it's great stuff, but I think it is an awful lot of work to do and entire ski base.
I think if you could drip a fairly level coating, which seems like an impossibility), you would still need to iron it on, which is trickier than Ironing on cleaner or glide wax. You would likely have to get a riller and rill the base also - "Course I am not an expert on replacing bases.
It is probably much less troublesome to just get a pair of wax or no-wax ski's on sale now - The end of season sales are starting to come up.
