I initially had that problem with Enduro, but I started using Tripoli as a first step in buffing, and it took those lines out. The suggested instructions that came with the Enduro said to use only white diamond and carnuba. I just can't stand the smell of CA and it burns my eyes too much; plus, I can't seem to keep it out of the bushings. I guess, like in all things, I would develop a technique with time, but the smell gets to me.
