Update on trailer lettering peeling within six months......I have the trailer now so I can remove the vinyl. I have more pictures, but all of the peeling is from the top and into the sides. As I remove the vinyl, I have to use heat because it's coming off hard. ( sticking very well. ) The customer says the trailer used to haul apple juice until it was wrecked. It sat for 4 years under a roof or awning before he bought it. Also, He said the other day that he and his wife washed it with Turtle Wax Car Wash before bringing it to me for lettering. I didn't know they used a Turtle Wax Car Wash. There are many types of Turtle Wax Car Wash and I tried to read online what is in their car wash soap. I found a couple or their washes that listed some type of silicone and others mentioned Wash and Wax. He said it was their CAR WASH, not CAR WASH and WAX. I didn't use a silicon and wax remover because I didn't know they used a Turtle Wax product.
I tried to contact 3M via email to show them the pictures and haven't received a response after two attempts.
I also read somewhere that some tankers have a clear sealant on them to protect them from contaminants. But the vinyl material and masking tape was sticking very well when I applied the lettering, and it was very hard to get the material off that wasn't peeling. Usually, if there is wax silicon, or some type of petroleum product on the surface, the tape will not stick at all and the vinyl doesn't stick as well. This was put on outside in 80+ degree temp. It was sticking very well.
So, I still do not know for sure what caused the peeling in less than six months. We did have rain/sleet/ice/snow within a 3 day period just before Christmas.
What are your thoughts?
Thank you
