I wish to overcoat house exterior doors(Wooden) & garage door(Metal) with glossy pastel green shade. All doors are currently coloured Bright Red.
What is(are) the best colour(s) of undercoat(s) to obliterate the red gloss finish ? Would I need 2 coats of undercoat ? Does the red need to be thoroughly obliterated prior to top pastel green colour being applied ?
Any assistance would be greatfully received.
