I have a pontoon boat that is showing a lot of oxidation. What is the best
product for restoring the shine to the finish?

You'll get as many answers as there are people with opinions.

Bare-metal aircraft people use a variety of products. The Aircraft Spruce &
Specialty catalog lists

Maas Aluminum & Fiberglass Polish
Flitz Aluminum & Fiberglass Polish
Rolite Metal & Fiberglass Polish
Rolite Supra 90 Aluminum Polish
Met-All Aluminum Polish
Alumin-Nu
Jet Stream Metal Polish
and probably a few I missed.

Note that for large surface areas, the pros use specific buffing machines
(quite a bit different from the consumer type machines, and more expensive).
Aircraft Spruce prices range from $259 for electric to $493 for air powered.

The following are also avaialbe at auto parts stores:

Blue Magic
Eagle One Mag/Chrome/Aluminum Polish
and probably a lot more.

With a job as large as yours, perhaps you could go to the local airport and ask
what the shops there use, and maybe ask if there's a service that will do it
for you. Somebody polishes those bare-metal airplanes, and chances are it's not
the owner.

You should find out what exactly the pontoons are made of. Some are
Alclad, which has a surface coating (can't remember what) and if that is
removed, the base metal corrodes quickly. Grinding or sanding is a
no-no.
Are you _sure_ it's oxidation? It might be some form of pond scum or
local hard water condition. If it's really corroding, be sure to check
any riveted or bolted connections for fastener integrity. Check the
welds, to.  Be sure the zincs on the hull or lower unit are still there
and replace them if they are more than halfway gone.
You might want to check the local marinas and see what they recommend.
Any form of corrosion on a small hull is cause for immediate concern.

Regards- Carl

Don't know what they are, but might help cleaning my aluminum sheets I
just might use with my "new" satellite ribs I got outta the desert.
The way prices are going I might as well do the heat part for next
winter. Only thing*** me up is , it has to be in the middle of
the roof, anyhow.  

Pete, what kind of plane do you have?   Must have missed it, only hear
you don't like experimentals. Trust me I am bias towards proven
concepts. My "in law" is into air coupes and I can't seem to get
there. We stole one from a doctor that was afraid to fly it once.  I
couldn't stop from laughing at the controls.  Funny thing is he wants
me to build a plane.  Kinda like an ultra light that the wings fold up
and can be towed backwards to an open area.

Sun shines , people forget.

The cladding is a layer of pure aluminum,generally 1 1/2% to 3% of the
total thickness of the metal.It is more resistant to corrosion but does
not have the mechanical characteristics that would make it suitable as a
structural member.

I have used Solvol-Autosol for polishing bike parts,but I suspect that a
guy could go broke buying enough to do the pontoons.It works well to cut
through the corrosion and buffs out well though.

 You would probably be best off to pick a color you like and paint the
pontoons,after doing any prep and anti corrosion treatment that can be
done.At the very least a coat of zinc chromate primer,but you could look
at alodine treating as well.
 The oxide layer that forms on Al.serves as a protective layer,to some
extent,and you will have to decide if you want to spend money or time to
solve your problem.It's probably going to take lots of one or the other.

Thanks for the info re: Alclad.
I'm really concerned that his hull is "showing a lot of oxidation".
Aluminum hulls should _not_ exhibit this.

I recently started using 3M aluminum restorer & polish and like it better than
anything I've tried.  Get mine at Walmart in the fishing/boating dept. I use it
on my antique feathercraft boat and antique outboards.

It depends on wether "showing a lot of oxidation" means it has gone
dull,instead of being shiny,or if it has grey and white crusty chunks
flaking off it.

If you want to get a  really, really bright shine use india ink.  It's the
latest technology from NASA for making telescope mirrors from aluminum. :O)

Mothers Aluminum Polish - My scout troop helped polish the B-17 at the Yankee
Air Museum at Willow Run Airport last weekend. (There were about150 volunteers
there to polish the plane). Mothers Aluminum Polish is what they instructed us
to bring to polish up the plane. When we were done they let us go through the
plane. It was wonderful to touch the plane and not be scolded. It was more
wonderful to talk to many there who served in the B-17 and other planes at the
museum. Most of the kids went back to polish after lunch even though it wasn't
necessary.
