Painting Aluminum Door frame

[Saltyric]

The "powder coat" in the frame of the door to my CC is all flaking off. I was thinking of sanding it daown an repainting it. Possibly with Lower unit paint or something. Any suggestions? Other than having it re powder coated. Thanks,

Am looking at the same question for the aluminum sliding door into the salon. Will post up info when I can dig it up.

We have aluminum parts powder coated all the time ,and I still am not a big fan of it ,I have seen it hold up really well and Iv'e seen it fail quickly too. One of the problems is dissimilar metals ,stainless screws in the aluminum frame ,you might notice the powder coat blistering around the screws ,tefgel is a product made to help the problem ,but we use 3m 5200 in the countersink ,This does a couple things I believe it sort of lubricates the screw in the countersink and does not "break'' the powercoat (when tightening) ,it also seals out the water ,if the holes in your frame are not countersunk and use pan heads you can use nylon washers to separate the two metals,If it was mine I would use Awlgrip ,this is a lot more work time and money ,sanding/alodine/priming/painting ,

I hope some more people chime in on this topic. I just finished building a home on the ocean. The doors are about 1 year old and already are peeling. My customer wants them replaced or repaired. ODL supplied the the impact resistance glass and frames. They cannot be remove, you will rip the door apart. The powder coat job was a cheap process, on a scale from 1 to 10 it was a 2.

We have decided to sand/scrap, prime with Ospo and refinish with Imron. Cost = $85.00 each

Try Rustoleum. I have good luck with it lasting pretty good on aluminum and it is very inexpensive as compared to other paints.

Sand it down use a good etching primer for aluminum and then paint. The primer is the most important step it will increase the durability of the paint to metal bond a thousand fold.

Ithink a good powder coating job is the way to go ,I re powdercoated my sliding door frame on a Jersey Cape 36 3 years ago and it is still perfect and has been outdoors since,however if your going to paint it and you want it to last you absolutely MUST etch with a part A and B aluminum etching product , I've used the system by Dupont, just painting alone will not make it even one season.

If you could have it hard anodized that is the way to go. It is the most durable finish for aluminum it for lack of a better term becomes part of the metal it wont come off but it can be scratched through. A second option would be bed liner coating you can get it in just about any color and it is tuff as hell.
