I used it in the past...and when I did have peeling with the masking, it also pulled up the Metalizer with it. I have since switched to Minwax clear gloss lacquer(thinned about 50/50 for airbrushing), for ALL my glosscoating, including over Metalizers. With an NMF...I'll gloss/seal, then mask for other colors, using Tamiya tape...but I do de-tack the tape by sticking it to the palm of my hand a couple times...that has almost completely eliminated any peeling issues.
