Thank you tc3team,
On asphalt with WGT foams be sure the track is prepped, clean with lots of sugar water
(we use that, I have little experience with soda)
Tires clean & dry NO additive works best for us. A practice or two to run them in. Additive's do not seem work as well as none. Imo.
Rubber tires, I have not tried yet. I will be trying typical touring tire additives.
Any suggestions would be great.
