Check out the Original Brochure for the '77
Boler in the Document centre. It has a couple of pictures and as
sold prices you might find interresting.
I would agree with Raya L, that it looks like it may be original gel coat colours. It will always need to be cleaned and polished to look new, BUT, if painted, it will always need to be repainted after a few years and then cleaned and polished to look presentable. That is a nice colour combination and I would try to bring back the colour before changing it.
Remember the old addage...." If it ain't broke don't fix it."
