Vinyl graphics will not stick to UPC Panels on box trailer? advice please.
I could do with a bit of advice on making cut vinyl graphics/ lettering stick to the side of customers box trailer?.
The trailer panels appear to be made of a type of PVC plastic sheet which has a very slight orange peel texture to it, after do the usual prep before application i then apply the graphics which go on, but easily peel off with your fingers even after leaving them for 24hrs.
I was advised to try a primer (3M Primer 94) which you apply to the pvc panels to help with adhesion, but after applying a test coat on one corner of the trailer the results of applying the graphics where the same.
The trailer has evidence of a trailer makers logo that has been on before which i assum stuck ok?
In the 25+years of signs making I’ve never come across this problem before.
Vinyl used is a 5 to 7 year which i’ve had no problems with before.
I look forward to any helpfull advice that anybody can give me.
