Left you a reply with a pic in your Mig Killer topic.
Seems that whatever works for one person doesn't work for another.
I forgot to mention that I had no problem with masking over the MM metalizer sealer with a very low tack mask.
I do agree with rjk in that any type of sealer tends to ruin the NMF finish. Maybe because of the way the pigment reflects light from each little piece of pigment as they lay at different angles, and the sealers tend to blend them in together. I don't know, I'm just guessing here.
One of these days I'm going to build three cheap A/C of the same kit and finish them in different ways. The only way for me to figure it all out.
Sorry I can't be of more help.
