Refinishing Delaminated GT tailights (Page 10/10) Adjustso3 SEP 29, 01:12 AM One last question. After the lens is wet sanded and masked is anything used to clean up the residue from the wet sanding ? I was just wondering so the urethane doesn't fish eye or bubble from the lens not being 100% clean. Should it be wiped with paint thinner ? Also when wet sanding should a little dish soap be added to the water or just use water without the soap ? Many thanks in advance.
