refinishing exterior windows

Have a 2000 Defever 49 CPMY. Exterior window frames are wood with screws and bungs going through the cabin wall holding the interior wood trim. Bungs are just starting to give way, making some small cracks around the heads. rest of the paint is in good condition. I need to sand this down and reset the bungs. wondering how to get a good match to the gelcoat next to it. They match perfect now. Maybe it is gelcoat on the wood frames. Was considering using Alexseal for the paint, but again need a color match or compliment. Anyone done this project before?

Nobody that I know of would gelcoat wood unless itís glassed and exterior trim like in the photo is a poor candidate. In fact I doubt youíll find gelcoat used on any of the deckhouse. These deckhouses are built up and not a molded structure. Those yards cannot afford or is it worth the time and effort to tool up such a complicated and fragile mold.

Iím not sure what material is used to build the deckhouse but you can find out by locating a vent, or shore power connection finish plate. Remove it and look at the cut out in the panel which should reveal either plywood or a sandwich with balsa or foam.

Anyway I only see one proud bung and itís being pushed out by the fastener below. If there are a lot more than you may have a problem. You could very very carefully pop that bung, if itís wood, with the white coating intact using a small sharp fine tool. If the bung is putty it still may be possible as the photo reveals it seems to have broken free 360į but you have to wonder if itís bonded to the screw head. For a small finesse job like this all these considerations are important if you want a quick easy aesthetic fix. The bung has popped because the fastener underneath is working and loose.

Track down that fastener on the interior and see if a similar problem exists. Iím sure itís a flathead machine screw nutted inside but it may be a screw if itís nutted inside so you wonít be able to tighten it but look anyway. Either way the screw must be re-torqued/tightened then with real finesse apply some glue and reset the bung. If you are careful to realign ( similar to a pottery chip ) the bung and attached paint will seat with very little evidence. If afterwords it looks a bit rough around the edges take some BonAmi cleanser and rub the area until you get a white slurry and let it set up and dry. Wipe with a wet cloth gently and wax. If this fails it would suggest taping off the frame, sanding with 180-220 grit and spray the same color with a PreVal throw away spray unit.

Good luck
Rick

I rebuilt all my windows on our blog, grandbankschoices.

With Awlgrip the window frames now look molded in.

Choices,
Did you use some fairing compound to do a filet between frame and exterior wall? If so you must have ended up painting it all. Big job for sure.

Not sure what you mean.

I used a fairing compound to fair the frames after priming mounting, and the bungs installed.

Then reprimed and color coated.

I used a urethane sealant between frame and cabin. Then masked 1/8" extra to allow paint to seal completely.

I did not leave a fillet from frame to cabin. Kept it a sharp clean 90. That will hide any imperfections.

Any questions PM me and I will send my number and we can talk.
