Eetu - Thanks for looking . This is my first use of the MetalColor line and so far I like them very much. It may be too early to tell about long term adhesion but I believe they will adhere very well indeed because of what I witnessed at the Vallejo tutorial/demo at the IPMS Nats . Both the gloss black surface primer and the finished MetalColor need to be lightly dusted on at first then built up a few minuits later after the first coat has tacked off. At the demo they masked with tape after a few minuits time and pulled the tape of with no paint coming off- while I don't advocate this it was very impressive and leads me to believe that adherence will not be an issue . I have only tried their clear coat - Metal Varnish is their name for it-
on a small test sample . It lays on beautifully but I think the finish looks better without it. It may be unavoidable if you are decaling . Hope this is of some help.
Sound good! I think I need to check those metallics out.
