There was a product a few years ago that was a spray, but I didn't think it was very good compared to just waxing skis.

Also have you seen a compact waxing iron anywhere. I've been using a regular iron for the last many years but it takes a lot of room in the boot/ski bag.

I have not seen any independent written test reports to contrast and compare the two... the advantage to this wax appears to be the lack of work needed to apply it and the lack of chemical hazard associated with working with it... working with traditional hot wax is considered hazardous unless you wear a respirator or have excellent ventilation.

An independent analysis of the two systems would be interesting to read...

For racing purposes I do not know if anyone has ever used it, but then again the 'mystique' of traditional wax has been both scientifically tested and mythologized at the same time... the latest scientific method I think being used is to physical test a variety of waxing choices on a ski on the snow to be raced the day of the race and then making a choice based on what the waxer thinks conditions on the snow will evolve into by the time the race occurs.. a scientific guess at best .. although most waxers I think use the 'secret' formula guess routine based on years of experience but little scientific documentation.. the secretiveness of the racing waxing community has not helped clarify the issues involved with waxing.
