i letter dump trucks for a paving company and i have yet to find a vinyl that doesn't burn up over time.
i have used orajet 3751 and also orajet 3591GHT both of which i have gotten no more than 2-3 years before it starts turning brown from the heat of the asphalt.
they were both digitally printed and laminated with the appropriate cast lam not sure if it's just the laminate burning or both the vinyl and lam
interested to hear what others have to say on this one
