Paint or Portlights. Which First?

[Jim Arthur]

Here's another question about a total refurb. Should I install new portlights before or after I paint the interior and exterior? I can think of arguments for either way, but I haven't been able to find anything definitive.What experience have others had?Thanks,Jim

Probably paint first

If you are installing plastic ports and therefore using silicon bedding compound, likely it's best to paint first. The silicon bedding compound will not hold paint, and it can cause paint adhesion failure on gelcoat wherever it touches and cures. Clean up any squeeze-out quickly if you bed the ports before painting. OTOH, if you use bronze or stainless ports you can bed with other compounds like polysulfide, allowing you to paint later.Fair winds,Wulfes/v Jenny Anne

Neither.

Unless you are installing exact replacements it is a three step job. I made such a mess fitting a couple of portlights(I replaced ten) that I was glad I did not paint first.I suggest getting a good fit and epoxying the frame perimeter first. Then remove the portlights to paint the cabin trunk. I used plexiglass and silver tape from Lowes to cover the inside of the portholes. The tape with the paper backing, sticks really well but does not leave residue like duct tape. This kept paint and other debris out while it dried for a couple of days(without rain). With the portlights out you can roll and tip uninterrupted by anything sticking out. Using Interlux Toplac I was able to get a spray-like finish. Take home a locker cover to practice on, especially practice on the vertical. Then I used Brightside with Interlux non-skid for the top of the cabin. Probably one quart for two coats. Good luck.
