Shady business practice.
Spanish graff artists started Montana Colors and developed the first fine-art spray cans for the graffiti market. The were popular, and distribution deals were made, one with a german company, L&G. This german distributor then worked with Motip Dupli (known in the US as Dupli-Color) to make exact-copy bootleg montana paints. Dupli tried to buy spanish Montana, was turned down, and then took them to court, saying that they had equal rights to use the Montana brand name. Then they found a Swiss company that had registered the name Montana (for something else) and payed them a royalty to use the name, and then took the Spanish company to court demanding the name and market shares. The original Montana changed their name and markings to MTN.
So, now we have Spanish Montana (MTN, Montana Colors, Hardcore, 94, Alien) and German Montana (Montana Cans, Montana Gold, Montana Black, Montana Platinum). Both are high-pigment, fine art paints, with a large variety of colors. Both support the street-art/graffiti scene. Both are available online. I much prefer the spanish paint, MTN, both ethically and in practice (MTN 94 is, hands down, my favorite paint).
They sell direct to the public from sprayplanet.com
(and no, I am not affiliated with them… I wish!)
Belton Molotow is another fine-art spray paint with a wide color-range that many people prefer to MTN/Montana, and may be a better option for cold-weather painting.
