Pretty good sequence there - what is used to prep the cab before applying the decal?
I basically sanded, primed, filled, sanded, filled, sanded, paint, sand, paint......then a light sand (scotch bright pad) prior to installation (tag rag first)...
Great photos Mark...I have not seen those before. It certainly inspires me to follow suit with the dry method.
I take it the centre (coin door) decal should go on first to assist with lining up the sides?
I'm seriously considering building a wooden filler to help as I can see issues with out it.
