Hello. Those of you who have polished aluminum airplanes, have you applied any decals over the polished aluminum? I have read warnings that decals applied over polished aluminum could lead to corrosion, while others say that it has not been an issue. Thanks.

Certain types of vinyl are now available that have air passages built into them. Sone exampkes are 3m 1080 and Vivid.

This issue has been discussed in great detail on the Vans RV forum which i frequent. The consensus there is that this is not an issue if your decals are made from these new types of vinyls.

I recently did a partial vinyl wrap on my plane. I have no concerns about corrosion after my research.


Thanks very much for the detailed reply. I did a search on the Vans Airforce website but did not find this info. I will try again. I am building an RV-12iS and I plan to polish the aluminum and add some decals. Thanks again.

The info. is on the Vans "forum". You have to sign up as a member. In order to sign up (its free) you have to answer a simple RV question which you can get by an internet search.

Since i have a lycoming engine i signed up and over the years i have gotten so much good info. on so many subjects related to building and flying.

I post questions on there all the time because they have thousands of members that can provide a wealth of info.

Although they dont encourage non-RV members, though dont kick them out.

I just dont mention that i dont have an RV (or  a Zenith) when i post a question and its never been a problem.

Its such a valuable web forum for home building, flying, destinations pretty much everything related to flying. 

You can post just about any question and youll get very knowledgeable answers quickly. Its really worth signing up because its a tremendous resource.
