I have been looking for a replacement for the vinyl edge trim used in my '74 Argosy. Obviously after 34 years of exposure to the elements the trim is cracked and broken out in many places. I came across this material in a local lumber store "Menards" that looked like it would work. It is slightly wider than the original, but I thought it would work. I installed it yesterday and think it looks good.
It is sold in the area of the store where you find interior paneling, an 8 foot piece was less than $3. I've attached a photo.
