Sounds a bit like the ole Maplus World Cup Reserved Soft-Med Base (40% soft, 60% med blend). Which basically halved base prep cycles versus doing an initial soft base prep cycle and then use the race base medium. You can simulate this by ironing on a blend of soft base & harder wax at a similar ratio. Since they've come out with the Xsoft saturation base prep wax which is even softer. I think of it as adding a lotion to your bases that soaks in before adding a harder protective wax. It is recommended for hot boxing or for *'the pseudo hot iron/hot boxing' method.
FTR, Maplus used to also supply a green base prep which wax like waxing epoxy into your base but provided bomber protection and lasted forever. Using a green wax is an option for added base protection & prep.
*Pseudo hot iron/hot boxing: For new skis (which I just went through) and for freshly ground or repaired skis:
- Clean the bases.
- Liberally apply Maplus Xsoft base, Maplus Soft red base, yellow or other soft wax you or already have in your kit. (Alternatively blend soft & hard to end base prep steps at 8.)
- Iron in a few or more passes to work in wax and heat up skis or snowboard.
- Perform a Light Hot Scrape to remove excess wax and save a little scraping later.
- Iron in a few or more passes.
- Let cool for 15-20 minutes
- Iron a few or more passes & let cool.
- Repeat or scrape & brush thoroughly.
- Hot Touch on a harder base something like Maplus Race Base Medium, other durable base prep (ideally) or a purple/blue glide wax.
- Repeat steps 2-8.
- Apply your WOTD or just ski on the wax used in step 9.
The other day for new skis, I added a blue WTOD after Xsoft & RBM cycles and the skis were fairly fast and still show very good coverage after 23 miles and 21K vert on fresh & softer snow. I could ski another day probably, but ideally, repeating waxings after initial outings, especially after abrasive snows, will help to 'keep seasoning' the bases and increase glide more and more. With durable waxes, you can start to minimize the number of times you really 'need' to perform to possibly upwards of once ever 4-6 outings.
For those who get their bases ground, can lose this build up. My recommendation is to not regrind the base if have them running well....even if they look like the've been in battle. Skis are tools, not jewels.
