i was thinking of repainting the metal frames around the windows and door of my f-32. is there anything specilal i need to know about what type of paint and prep. thanks
In the middle of this job right now.
Search the forum and you will find several threads on it. Some recommend zinc chromate primer for the aluminum frames, but that is either hard to get or illegal in some areas.
I went with (am going with) :
- scrape any loose or flaking stuff off
- sand
- solvent wash
- (Interlux) Interprotect 2000 for primer
- sand
- solvent wash
- (Interlux) PreKote for a undercoat
- sand
- solvent wash
- (Interlux) Brightside Polyurethane
- sand
- solvent wash
- 2nd coat of Brightside
We are doing all window frames on the F32, including salon door and frames.
We got as far as first coat of Brightside in the fall before temperature and humidity conditions made us stop. Looks WAY better than it used to. We are about 4-5 hours per coat with 2 of us working on it, plus sanding/vacuum/solvent wash time on top of that. This is with everything already masked off. Doing the job by hand with brushes. Don't trust myself to be able to control overspray.
Once we get the temp back in the spring, we will finish the job before launch.
Only one oopsie so far (when *someone* dumped a bunch of PrimeKote on the cockpit floor), but after yelling at each other for a few minutes and half a roll of shop towels, all was good again.
One other observation - DUST is a bugger. We are stored indoors, so don't have to worry about wind, bugs, or sunshine heating things to cause uneven drying. But we still have no good way of controlling dust in our shed. I thought out first would come out total crap when I first saw the dust accumulating in it, but Brightside did a good job of levelling out and hiding much of it. Hopefully in the spring when others have launched, we can control the dust better (maybe hose down the walls and floor in the area of the boat).
