Guys — I feel for you having traction issues on new SP.ED. RCP…
That’s not what I would have expected from RCP? If the material looks the same just a different color, maybe it is just chemical residue or dryness all the way thru? I have found vacuuming with a good vacuum (>Powerful, not the have-dead vacuum in the garage) the RCP-material gets a little re-newed or something because I love running after just vacuuming the RCP (vacuum part blows though..
)
If you have a spray bottle with water and mist water (just a little) over the entire track - Not wet, just to get moisture in the air. Let sit 10minutes; Vacuum. If these 2 things don’t work, I would get in touch with RCP.
