Default Polishing under the aircraft

Several of my friends are sure I have lost my mind, as I have decided to polish instead of paint my RV.

Has anyone tried this product for under the wings and belly of the aircraft?

Thanks

Yes I've tried the purple polish. It brightens up the belly a bit when used by hand with the green oxidizer treatment. It's not a replacement for a full nuvite compounding and polish. I was using it for the bottom of my unpainted RV8 after trying to hold a buffer above my head...

As a polisher myself, I have to inform you that your friends are correct.

If I were to do it again, I would have taken Jed Gregerson's advice and painted the underside of the plane.

HOWEVER....

At Oshkosh this year, a gentleman saw me land on 36L, and noticed how the underside lit up purple first and then lit up yellow as I passed over the dots. He finally made his way to homebuilt camping at which time he said, "I've been looking all over Oshkosh for this plane."

So, bottom line: If you want to spend hours polishing for a few minutes of delight at Oshkosh, polish away.

To answer your question: I've used both. I wouldn't use the purple polish anywhere without using the green stuff first. I don't know why, exactly, but it comes out better.

The underside, especially the wings, take a real licking where polish is concerned. Overflow from the fuel tanks runs down there. Occasionally a dribble from spraying leading edges when removing bugs gets down in there. Even smush from the wheels gets kicked up in there. so you get water spots and some corrosion.

So, once a year, you're going to want to compound it with NuVite.

Default It's all Bob's fault ...

After reading Bob's threads awhile back about polishing, I too got sucked into the polishing abyss. I'd always loved the look of a polished plane, and Bob's experience was just the incentive I needed. Here's a few of my observations after 15 months of polish experience:

- Nothing creates the mirror-like finish on aluminum like Nuvite, but Purple Polish (with the green oxydizer) gives a "decent" appearance for 1/30 the labor. If you've not seen the shine produced by the 3 step Nuvite process, you might be happy with Purple Polish.
- I've used the Purple Polish on some rough areas, and then followed it with Cyclo'ing using S and/or C Nuvite. It looks amazingly good.
- Regarding hours necessary for the Nuvite process, I've found it takes about 1 hr per sq ft (that's for the full 3-step Nuvite treatment). For underside areas or difficult-to-reach places it's more.
- Despite warnings from several who "had gone before", I was surprised by how much work it is even using power buffers. The buffers are heavy and/or require a lot of opposite torque, and - in a warm hangar in the summer - will make you sweat a blue streak.
- I agree that the underside is much better to paint. I will also paint a fair amount of the wing top side to reduce sun reflection. I've had afternoon flights where the reflection off the shiny wing virtually fried the side of my face.

Default Don't Polish the bottom

When I was buying my polishing kit from the Nuvite booth at Oshkosh, when I told him it was an RV, the Nuvite guy himself said "paint the bottom". I took his advice and am glad I did. It's all I can do to keep the tops-side polished.

On the other hand, there's nothing quite like seeking shade under your RV wing at Oshkosh on a hot day, and looking up at... you.

It's a sickness... Every time I polish I am look over at the spray gun and think I could just end this madness. I use the Nuvite process, best to keep up with it rather than having to do a full compounding and polishing. The cyclo polisher works well but gets heavy after a couple days but you can polish the polisher when you are done with the airplane!

Fortunately my RV is painted but here is my other airplane.

I notice that Perfect Polish is now carrying a brand I've not heard of before.

Has anyone tried it?

BTW, for some reason I was surprised at the show special NuVite had on polish -- I think it was $45. For some reason I remember it being $35 or so not long ago. Am I dreaming?

Instead of painting the belly, couldn't it be polished, cleaned, and clear coated?
