Getting my newly re-covered interior back this week, And I was wondering if anything can be done to protect it from future sun damage? Does ArmorALL do anything, or just more damage than good? Also, can I just put the same sunscreen made for people people right on the seats and sundeck? Seems like some SPF 50 whould work just as well on vinyl as it does on skin. Boat is stored inside, so that is not an issue, but it will soak up a lot of sun during those long days on the river. Any ideas, or do I just need to re-do the seats evey 25 years?
