Here's how I'm prepping my daughter's brand new skis (Blizzard Viva Jr.). Clearly, this isn't the textbook approach, but I'd like to hear some constructive criticism from experienced folks. I'm not so much interested in the what and how as I am in the why.
1. Wipe down with base cleaner (Tognar citric/naptha blend)
2. Flat file with SkiVisions File Base Flattener, tip to tail
3. Sand from tip to tail using wet/dry silicon carbide sandpaper wrapped around a cylindrical "block" (Curv A Flex). Progression: P80, P100, P120, P150.
4. Raise hairs by working synthetic steel wool from tail to tip.
5. Melt hairs using an inverted propane torch with a flame spreader, carefully.
6. Use SkiVisions Ski Base Flattener to remove melted hairs and impart final structure.
7. Establish 1-degree base bevel with a Sharpie and file (Vallorbe IceCut Bastard)
8. Establish 3-degree edge angle
9. Polish edges with variety of DMT diamond files
10. Wipe with base cleaner
11. Hot scrape 2x with universal hydrocarbon wax
12. Wax with Toko red hydrocarbon followed by light, hot scrape
That's where I'm at now. I'll do final scrape/brush right before use.
My concerns are: (a) getting the hairs without melting pores in the ptex, and (b) will they ski fast enough. I'm wondering if I should have added some aggressive metal roto-brushing after step 5 or 6.
