Preperation! Preperation! Preperation!
Make sure the wheels are prepped thoroughly, sanded and really smooth use a green pad or similar. Then put a thin wipe of white spirit or similar to remove all grease or finger marks, then primer. Fine sand with a wet & dry or similar then primer again then topcoat & Laquer.
Show pics of each stage if you can, to give a useful guide for other members on here.
Good luck....it gets really boring after the first wheel is done
