Dave, I got my F-86 decals from Squadron.com. Specifically, it's the sheet produced by Aeromaster (#48-749). I'm going to do the F-86E with the markings for "The Chopper". I've just always liked the name of that plane.
Otherwise, you can't go wrong with Aeromaster, Eagle Strike nor Cutting Edge decals. You can find those at places like Squadron and Sprue Brothers. Ebay is another good source as well.
As for paint, not too long ago I finished an F-89 Scorpion (Monogram's 1/48 kit) using Floquil's "Platinum Mist" and "Old Silver". It was first time ever using that brand. I had seen others on this forum posting pictures of their models using those paints and I thought they looked great. It was enough for me to give them a try and, lo and behold, I am a convert! They went on like butter and didn't have that grainy metal flake look to them.
I know that several forum members have used Tamiya silver (AS-12 I think it is) and it looks pretty good. I've never used it myself but I saw that you like the Tamiya brand. Personally I'm a Model Master enamel guy but their silvers, while good, are very touchy and can't be masked over as well as Floquil.
There is a brand of paints out there called Alclad that people swear by. I've only used it twice: Once with phenomenal results and the other with lousy results. They come in many different shades of metalic silvers. I do believe they are a laquer and they go on quite hot. It's generally advised that a person lay down a base coat of paint first rather than applying it to bare plastic. Otherwise, it could mar the plastic. That's just what I've read in the past.
I don't know that I'll back to that brand. Like I said, some people swear by it but personally I find that the extra prep work just doesn't sit well with me. I blame my natural inclination towards laziness. Also, if I have to add a flawless base coat, then it's just an additional step that I could possibly screw up. But, if everything goes well, then the results can be amazing. I think it's kind of pricey though and it can seriously kill brain cells if you inhale too much of the fumes. I know all the other paints will do that but Alclad paint fumes seem to be particularly cringe-worthy.
I hope this has helped! I hope others chime in with their experiences with NMF paints, too.
