Default Restoring ALuminum Outriggers

I have a set of Rupp outriggers that are a little older and I would like to restore them to as good a finish as I can.

There is no real electrolysis pits but they are dull and have some very light spots.

Id like to get them as good as I can then ceramic coat them.

Ive got some flitz and a power bench buffer to go to town on them.

Any trick to bringing these things back?

Can you wet sand them ?

Thanks

Well I figured out you can in fact wet sand them. The flitz alone did little, but when I put some 400,600, 3000 sandpaper to it it came to a near factory finish.

gonna take some work tho.

Great job Cap...
Keep us posted on your trial and error. I need a freshen mine up, they're not in the shape yours are in, so I can probably start from your last step and get a factory finish on mine. Let us know what you use for a final protection coating to prolong the shine.

The finish looks good, but won't last. They normally come anodized from the factory (I think). That shine will dissipate as the aluminium oxide layer reforms. That's good in that it protects from further corrosion, but it will forever have that dull milky look.

Agreed. Theres no doubt
The whole concept is to get it clean and coat it w ceramic finish.

I am no alchemist but Im sure it is very "exposed" at this point and would not last long in the elements.

perhaps wax or alumaguard would keep it shiny if I kept up w with it, but im after a "put some hard work into this and them cover it w a hard coating" to cut down on maintenance and still have it look good

I‘m interested in how the ceramic coating goes. I’m just about to buy a set of used Rupp riggers and would like to know what would work restoring them.

You can have the outrigger aluminum re anodized. I got a price last year and it was $500 to re anodize both 32ft riggers. Biggest problem is taking them down and apart.

You could acid wash them and paint with Nylac or similar.

to have them reanodized do I have to remove oxidation first? or do they do that?

Not sure what the acid or product is called sorry. Have bought and used it from the local chandlers and there were several products to choose from. I think the last one I used might have been called Alumabrite or something like that. Worked well. Couple of coats and things looked pretty shiny again.

I looked up Nyalic
This is a very interesting looking product. Not too expensive either for hat it says it can do.
I may give this a try.

Can def see already that the protective coating will need to immediately follow the whole removal of oxidation and polishing. The bright finish I had yesterday is already starting to cloud slightly just overnight.

A guy here had them painted either in awlcraft or alexseal metallic, look good, unless you’re right on top of them you can’t tell they’re painted

No they do that with an acid wash. Part of their process.

Gotcha
I tried a few Dif types of acid over the weekend including a long vinegar soak. Did not seem to do much.

A chemical Wipe on wipe off would have been great.

I think its the anodizing that is damaged through the oxidation over the years. So far the only thing that get its to the high polished look is through mechanical means. I purchased a tube polisher over the weekend to make the process more efficient.

I reconditioned an aluminum gill engine bracket with an acid wash and anodize before epoxy painting. I think you can just use the wash that I give the link to below. Read the attached tech sheets.


BONDERITE M-CR 1001 AERO (FORMERLY ALODINE 1001)

You are on the right track with the wet sanding work you have already done. Next step is to clean the finish up using Dawn (neutralizes the surface for the coating to adhere to the aluminum), and then follow up with Showboat Custom Coating (ceramic coating). See their website for the application process. I did my outriggers 4 years ago, and they look as new. Granted, mine already were almost new when I did the job, and only needed a Soft Scrub/Dawn application before I coated them. But the point is they are still looking great with just regular boat soap and no waxing. Your riggers look like the ones on the Showboat video's, and they ended up looking new.

If you need help, call the owner. He was very forthcoming with info when I spoke to him.
