I would like your opinions We have our council race coming up over 200 cars We have had very good luck with graphite over the past 4 years. I've bought all our parts over the years from DD4H and his DVD. With all the cars in this race I'm wondering if our luck with graphite will run out. I hear there is a learning curve with oil do you think we should stick with graphite for his last race or try DD4H oil process with all the cars in this race?
