Removing spots on aluminum

[T1DMcure]

How do we get rid of this? Have tried Alumabright. This is the result. It had slight improvement. Would prefer not to polish and obtain a satin finish.

This has worked for us. Used a 6" Porter Cable random orbital polisher and a damp foam pad.

Ck out all Griot's products, been using them for years, 1st rate with great CS.👍

Just added photos. Thank you. They look like large drip spots all over.

[T1DMcure]

Any idea what the drip spots are?

[T1DMcure]

Thanks for the detailed info Bob. We have an orbital polisher. So can give that a try. The drip marks line up with the rivets.

On our Classic these were caused by the deterioration of the white roof coating AS uses.
I've used the One Step for assorted light blemishes on the AS panels.

I did 'Green Scotch Pad' the roof to help reduce it.

[T1DMcure]

Our roof is not white, though. The Griot product you mentioned says it is a sealant. We are only at the stain removal stage.

I’m contemplating ceramic coating the AS, any thoughts...is it worth it?

[Minno]

Have you removed the clearcoat?

Kay, we tried stripping it and nothing came off. Perhaps clear coat was removed by previous owner.

What has worked well for us is using WD40 on a 2020 25' AS Int. There are some who are not in favor of using WD40 but it has worked well not only to remove stains like hard water spots and dirt streaking but also to give the AS skin and good protective coat. If it was good enough for NASA, then I'm all in ! I only hand rubbed it in being careful to follow the grain direction wherever possible. Yes it is a lot of extra work but looks good afterwords. There are a lot of opinions out there I'm sure !

air_999,
How long have you used the WD40 on the aluminum? I've always done the stainless rock guards with WD and it always looks sharp. Didn't think it was good on aluminum.

[T1DMcure]

I've never heard about using WD40. Most likely something very acidic or basic make the streaks in our aluminum.

air 999 - do you use the regular WD 40 or the silicon-based WD 40?

Regular WD-40 on stainless...also good for removing bugs on the panels.

STREAKS...first determine are they on or in the aluminum.
If the panels have the ALCOA factory coating it's most likely a surface concern and light buffing with a mild product is in order.
No clear-coat and the damage will most likely need to be polished out.

WD40 on the segment protectors, Griot's One Step on the rest,(POI trying Griot's 3in1 Ceramic this Spring)

[air_999]

Regular WD40. Works well with no harm. I read several posts on this just shortly after we purchased our AS back let July 2020.

We bought our AS last July 2020. I have hard water where I live and where I wash the AS, one in the same place. I have used the WD40 three times now, covering the entire AS except for the roof. It always gets rid of the streaks and hard water spots. Always use a soft cloth (not towels) and I spray the cloth not directly onto the AS surface.

[T1DMcure]

Good info. Thank you!

[T1DMcure]

Good suggestion. We will try it.

What are your rivets made of, also alloy ?
Its posible that the aloy plate oxidises at the holesvof the rivets and residu is dripping by rainfall over the aloy plates.

Orbis every AS owner having these stripes.
