Main reason for repainting is looks. I am about to start a conversion/rebuild and convert it to a center console. Its gonna be a whole new animal when done, and i plan to paint everything inside and out. I am not sure how clean the bottom will be after sanding. But i have been thinking and i may be able to make my paint scheme work with a white bottom.
I do agree a white bottom looks better but i guess after staring at puke green and blue on the bottom for six years i am afraid of what it will look like white.
My paint scheme might now be white bottom with white sides and a blue boot stripe that splits off diagonally and runs around the bow. Only problem is this bow is so funky shaped, i will be painting almost two foot to get it to match the six inch rest of the six inch boot stripe. Here is a quick ms paint i did to try to describe it.
