Your airplane illustrates one interesting use of vinyl...a true bright chrome finish. We've all seen plenty of polished RVs with painted intersection fairings, tips, and cowls because there is no real good chrome paint, at least none I've seen. Silver doesn't match polished aluminum for sure.

You mentioned some increased difficulty with compound curves when using the Avery chrome film. However, it looks like you successfully covered the upper gear leg intersections. Being critical, do they look good up close?

Wrap vinyl also comes in clear, I believe sold as "paint protection film". Has anyone applied it over polished aluminum?
Thanks Dan. The chrome has less stretch. So rather then fight it around in one piece I have a seam with the gear leg intersections. I almost always have to point it out to the curious.

I have not tried the clear, but wish I would have instead of the yellowing tape on my flaps. I'm not sure what the other application might be for it, over the polished so I never touch Nuvite again? That might be nice.

I'm glad you asked. Sub-wrap corrosion was one of my primary concerns when I initially researched my wrap decision with Scott at AW. He has never seen corrosion under any vinyl. He has quite often taken other vinyl off planes that had polished aluminum with graphics and the aluminum under the vinyl has always been pristine compared to the surrounding areas.

Really nice Scott! Great scheme. The blue works great with yellow.

Has anybody wrapped an RV-12? It seems like it would be pretty difficult with thousands of non-flush LP4-3 rivets to deal with.

Default one more observation

Dan's right, a healthy dose of skepticism ain't a bad thing, when you are talking about your $100k project here. Saving on paint won't look that smart if the vinyl causes ANY problems that can't be dealt with.
All I know is; I have been sticking vinyl on things since about 1983. The stuff stinks! meaning, when you pull off the backing paper, you get a good dose of solvent smell. Some more than others. even those with 'acrylic adhesive' have some kind of 'liquid glue' in the formulation to allow the stuff to flow and reach it's ultimate bond. Note: when removing the adhesive from quite a lot of vehicles, nothing works better on this 'acrylic' adhesive than good old mineral spirits, or paint thinner. What does that tell you?

now, as far as, " will it kill my aluminum airplane"....the jury is out.
Vinyl graphics have been used on airliners for years..but we really haven't heard from those users what if any effects there were.

The other big thing that permeates many conversation here on VAF is this:

.........whether you have tires, a certain brand of canopy cover, or paint, or plexi, are we talking a plane that is in the sun for 20+ HOURS a year.... or one that is in the elements for 2000 hours a year?!?!?!
There is really no comparison in how a product will perform when it's indoors 99% of it's life, or if it's out there 24/7..... so let's not say things like
" there's never been a problem"....or " this stuff will corrode your plane" unless you are comparing apples to apples in temps and exposure.

my $.02

It's pretty hard to prove a negative. Just takes one contrary data point to disprove it. So I think we'd all be open to seeing any example somebody could provide of corrosion under properly applied vinyl wrap to intact alclad aluminum, under normal use conditions.

It may be there aren't enough data points and time in service to have a definitive answer, but we may be getting there thanks to people willing to experiment.

I always think about the corrosion some have had under the blue plastic wrap that is applied to aluminum sheet when it is made. There have been plenty of reports in this space about people having corrosion (minor to severe, depending) on blue plastic clad parts that have never spent a night out of doors.

Default Let's tear some off...

I have some yellow stripes I really never liked on the top ends of my wings. I think they look like a banana. They are applied over bare alcad and have about 300 hours flight time, plus another 1500 hours in the great outdoors. The rest of the time in a good dry unheated hangar.



So if a Metallurgist from the group would like to stop by...let's peal them off and take a good look.

There are many airplanes with no paint, polished or unfinished flying a lot longer than mine without the skins disinagrating, so maybe we need more time?

But peeling them back might uncover hidden moisture or...?
