I've been riding terrain park for a few years and have recently started noticing deep gouges in my snowboard, I never use to get these mainly just scratches. I'm thinking about getting a p tex wax, how well do p tex waxes work? I've never got one before usually just hot waxes.
Unless I'm totally out to lunch there's no such thing as "ptex wax"...
Ptex is base material that you melt into the gouges on your board, let cool, scrape flat, and then hot wax over. Unless the gouges are bad there's really not much of a need to ptex.
You could bring it in for a base grind and repair one day... I've got about 60 days on one of my boards and it's been over enough rocks I think it's ready for a base weld and grind. I attempted ptexing the gouge myself but it's in a heavily used area and about half the repair came out over the next rock.
