For our Awana car, we had the same issue with blue thunder. It seemed too waxy. After drying completely, we put a drop of blue thunder on a piece of the Selvyt cloth, let dry and GENTLY wiped axles. Keep in mind, we didn't wipe the coating off. More like very gently worked it in by slowly spinning the axles by hand in the cloth.
We used DD4H oil and spun the wheels. They only spun for about 5-7 seconds. So, I know how you feel. You're not sure whether it's fast enough. Once we started racing, I knew EXACTLY how fast we were. I'm sure the track had to be shortened, but our first 4 times were 2.85, 2.90. 2.92 and 2.9080 on our way to 1st place.
If you follow the steps that are outlined on this forum, you definitely won't be slow!
