i wouldnt say l.i.r. in particular, but just in general, ive got the whole compound/insert/buggy grip/simple green thing down fine, but maybe theres more to it than you or me might know, i never heard the motor spray in a bag thing ive tried simple green in a bag, that works o.k. i guess my main objective by creating this topic is to see if theres anything else that people are doing were there doing it and why, theres always room for more options, and seeing that tires are the #1 tuning option its definetly interesting to hear other peoples applications to there tires, and oh yea, almost forgot, the nats. are only like 3 months away!
