What is belting?

You've never seen a conveyor belt before? The belts are repurposed when worn out or broken. An appropriate size piece can be used for airdam and skirts. Sort of like mudflap material.

Thanks! Yes, I have...but was not aware that it could be repurposed to use on a skoolie!

with skoolies we get to do it our way - many of us are on a tight budget, so costs are important too - for safety's sake, what we do has to be safe and legal - for something like air dams that for best effect, have to be low to the ground, I can't really think off hand of anything more suitable than rubber belting - if you hit a rock or curb with it,it will bend and fall back into place - as long as it's well fastened at the top, no damage done unless the paint job needs a bit of a touch up - 3 or 4 ply belting is amply stiff enough to deflect air -using custom air dams could easily run into $1000's and rubber belting is cheap, or if you know the right people in the right places, it can be free
