My so-called 'Thinking' goes like this:
The supposed reason for hotboxing (other than the obviously sensible rationale of requiring yet another piece of ski maintenance equipment and the need for an additional several extra hours in the workshop fettling skis) is that by doing so, the wax penetrates deeper into the bases (how deep exactly - anyone have measurements for this ?)
However when I ding my bases one of the steps I do before patching is to rub down the area with a base cleaner to remove wax in order to improve the adhesion of the PTex filler ribbon to the gouge and the surrounding surface. This wipe down seems sensible if the wax is confined to the surface, but if hotboxing does indeed cause deeper penetration of the wax, won't that wax cause the PTex filler not to stick as well? And if it does penetrate more deeply, presumably it won't be easily removed by wiping down with base cleaner (Wait !! Maybe I've just stumble on the need for yet another piece of ski maintenance gear - a deep wax penetration remover)
Any thoughts ?
