Guys I used SXT for the first time today...we used it on 4 different cars all using sorex 36 tyres on concrete.First we used it as instructed by Paul Wynn
from P Dub...applied it 30min before race time with another application just before I raced,It worked well but not as good as expected.This could be because of other additives still in the tyres.Then we tried cooking it on with tyre warmers..much better.We all agreed that cooking it and adding another application just before race time worked really good.The temp was cold 11degrees up to 21 and remember this was on concrete.We will try on tarmac next week.
