types of vinyl
Attention to people who want inner tunnel wrap done:
There are 2 main types of vinyl on market: cast and pro calendared.
Cast vinyl is stable when applied to a surface. It harbours no tension, whereas calendared vinyl harbours up to 25%. Calendared vinyl is made by processing a mass of vinyl through rollers and stretching it over hundreds of feet. Therefore when applied to a curved surface such as a car, calendared vinyl will shrink back causing curling and other issues.
In contrast, cast vinyl starts off as a liquid and is poured onto a sheet and baked. This means the cast was never stretched to begin with and will stay in place for the life of the vinyl. When cast vinyl is accidentally creased or stretched, you can heat it and it will return to its original form without creases or stretch marks.
What all this means - cast vinyl is preferrable for flat or near to flat surface applications. It`s thick. Hell yeah, its thick. It has very good structural strength, and ideal for hard working surfaces. You won't be able to go around rivets though, so you need to cut holes for them.
You do want cast vinyl for this application.
