I have used vinyl spray on head linings with good results

Has anyone used them on seats??
It is not going to get a lot of use, but it will need to be fairly hard wearing

I have vht vinyl spray on my console which gets flogged eveyday by the gps and mobile sitting on it and dirt and sand gets on it quite a bit.

2 years and still hasn't worn through. once that stuff cures it become part of what its on.

This is for a rear seat that will have a dog jumping in and out

it will be fine.

just make sure you do about 5+ thin coats with the correct drying time in between. I found that works best.
