I’ve painted the body of my model car using Halfords spray cans but I’ve touched up some minor areas using the humbrol or Revell acrylic paints. Will I experience any problems using Halfords clear lacquer over the top?
I don’t know, but you can always try: paint some scrap material (a bit of sprue, for example) with Humbrol and Revell paints, then add the Halford’s over the top of it.
