I've ridden my board a total of 4 days (it was in one trip) and I never really took care of my board. So it's been about a year since I took my snowboard out and when I did, I saw some brown splotches along the edges of the base. I think it might be rust, but I'm not sure. Could I just file it out back to normal or is my board fubar??
yes it is rust. no your board is not fubar. get your hands on a diamond/gummy stone takes the rust right off those edges. or you can take it to a shop and have them do what they can. also depends on how much rust there is.
well i want to wax my board before i take it for a ride this winter and before i could do that i want to get rid of this rust. could i buy a diamond stone from lowe's or something? i just bought some stuff online and i don't feel like ordering and waiting for it to get here.
a tip to avoid this is to towel your base down real quick after your done riding. then you can also run a bar of wax down the edges as well. keeping water and oxygen away from your steel edges will prevent the oxidation process from happening so rapidly.
