Toko silver (one snake or two) and a squirt of Mr Sheen was all I used in dry slope races in the late 80's. Anyone else do the ESF Grand Prix circuit? Then Kings Uni racing '91 to '94.
The smell of Mr Sheen still gives me an adrenaline buzz after all these years! Memories of kicking up a ski for a mate to apply just before my run come flooding back. Great first run then get excited and blow it on the second - Mum always blamed too much Mr Sheen!
Also remember testing Black Magic - a black graphite paste with a working temperature, so it was like a turbo - 2 gates in and it took off! Washing up liquid worked a treat on the grass skis too.
To answer the OP, just get some universal hot wax and bang it on. Remember you don't want it on the base but in the base so apply a few coats, cool, scrape well and repeat if the skis need some love. Brush as well if you want to really fly!
