Product reviews published in the other two airbrush magazines are submitted by the manufactures not by those who buy and use the products.More of a sales pitch than review. The
only place you'll find reviews by the artist that actually use the products and equipment (artist not on manufactures payroll) is the product review here at Airbrush Technique, link below

Our product review is an on going project 24/7 365 days a year. It's a much more effective way (the Internet) to go about publishing airbrush product reviews than in a printed format magazine. Our product review will be what the members here make it, I hope you'll take 5 minutes to review a product yourself today.
Airbrush Technique Magazine publishes the best of the articles that are submitted to the magazine that fingernail has not appeared is because no artist has taken the time to submitt an article relating to fingernail airbrushing. Airbrush Technique Magazine will be what the readers make it.

Our on line magazine
Airbrush Artist Magazine does have articles that cover finger nail airbrushing.
To limit your exposure to just articles covering fingernail airbrushing you are selling yourself short as many of the technique's, business practices used in one aspect of airbrushing carry over to other aspects of airbrushing (techniques used by illustrators can be used by T Shirt artist, Auto art, etc. for example)
anything else just let me know
