Always liked those Blue and Whites, and your's is certainly a fine example. If looked after, the 1500 Valk paint jobs hold up exceptionally well... why not keep them looking as good , as well as running as good as possible? Mine has just over 200,000 km (124,000 mi) on her and has seen her share of weather over the years. I don't mind getting her dirty, but I just don't allow her to stay dirty. Always has a few coats of good wax on her, and I enjoy doing the detailing.
Don't worry though, I won't enter mine in the show next month...wouldn't want to lessen your chance at the hat trick
