I started a restoration on a 40' motor home for my neighbors. I am doing it for free as they are an elderly couple on a limited income. He was diagnosed with Parkinson's and she had a lung transplant. It is very oxidized and the vinyl graphics are shot out, faded, ugly and starting to lift. He has had it 9 years and "never waxed it or had it waxed". I have got the oxidation off and it's looking great, but the vinyl graphics look horrible. Any suggestions? Thanks
