Tbh brother. That's a good question, but I do not know the answer to that. Hopfully someone can chime in and help with this b.c id like to know to. I will say my truck sits alot and it's covered 100% of the time when not driving (living in AZ so that's pretty important). So I'd assume and hope it will last quite a while. I also wash my truck every time after driving so I'm sure that will help to. (No I'm not scared, my truck is strictly a family truck. I use it to make 2 hour+ drives mostly, really. Weather visit family back home which is 5-7 hours away, up north in the state which is 2 hours, the river to go boating 2 hours or desert to go riding/offroading 3 hours)
