ive been to a1 signs in galway recently.
they are printing me out custom vinyl , and i'd nearly swear the guy said the sheet of vinyl i chose was 1000mm wide.
it is a special vinyl , which is designed to hide previous art or posters that are on the item for covering.
the front of it is solid white and the rear of it , where the adhesive is, is grey . so no matter what you place it on ,
it'll block out filler holes , and bad colour imperfections.
what it wont hide is holes / lumps n bumps in the wood . i used a test piece on my cab and it sticks perfectly and hides
the filler holes perfectly ( they dont show through ). i'd ring them just to verify that you can get it 1000mm wide first.
