Aluminium Cabin respray

Hi can anyone provide some knowledge on the best way to respray an aluminium cabin, i have been informed powder coating is a no go due to pitting from air pockets and wondered if anyone could share any success stories.

You can powder coat aluminium but you may struggle to get an oven big enough & the heat may be an issue for accessories depending on what type of boat it is
Alternatively an etch primer then a reasonable 2 pack top coat should be fine

Powder coating also needs to be baked. Is the cabin removable or is it permanently attached to the hull?

It's removable but I asked a powder coating company and they said they wouldn't do it as they couldn't guarantee the finish

Might be worth a second opinion as powder coat is much more durable than paint & many aluminium items are powder coated
Maybe there was too much prep or the company just didn't fancy the job
Powder coat is electrostatic which helps get the coating into places you won't get with a wet system & often those places are where corrosion will start & creep under the coating
Is the cabin currently painted? Usually needs sand blasting to bare metal & to provide a key for the powder coat

I understood powder coating wasn't very marine-proof. I may be wrong, I've cause to go chat to the local powder coaters as the A-frame on my current rib is Ali so I'll report back.

We use powder coat on offshore equipment & it lasts far better than any paint system we have tried
Even on gear going subsea
