Testors Aluminum Plating.......

They do make a sealer. Perhaps you need to consider a more friendly NMF paint.

You can also seal with Future too.

Thanks, I forgot all about Future. 

What kind of NMF would you use? I have Alclad, but don't have my air gun set up....in the midst of remodeling the basement. 

I would strongly suggest Alclad. The stuff is very easy to handle when dry, and if you are even slightly competent with an airbrush it is not hard to apply.

I think Hawkeye also makes a similar product that is supposed to be pretty good, but I have not yet tried.

Thanks, I've briefly played with Alclad in the past and loved the outcome. About 5yrs ago I painted the fuselage of a American Airlines MD-80 with it and then packed it away before I moved. About two weeks ago, I was going through the boxes and opened it up and it still looks perfect. For a second there, I thought it was really made of aluminum and then it dawned on me I had painted it before moving. 

Once I get my bench and airbrush set up sometime in the next year, I'll get back to using the gun and Alclad. 

Thanks again for all the info.
