I'm in the process of redoing the inside of my '84 Pearson 303. I decided on one part Interlux Brightside
paint. I think one part will be fine for the interior where it is protected from the environment. I did not want to deal with the two-part
paint toxicity issues in an enclosed space. I've only used primer in the few places where I needed to do some gel coat repair (PO had a small galley fire). I used the compatible Interlux primer. I'm not going to prime the rest, as the cabin liner has a type of non-skid pattern that the primer tends to obscure. I am using Interlux flattener to dull the gloss. Finally, I intend to roll on the
paint where possible with a small roller, and will brush the trim and smaller areas as has been suggested. As for a two-tone effect, we decided to just
paint the liner from the ceiling down to the tops of the settees. This section will be in white. The lower glassed areas will remain off-white.
