Just got my upper and lower back from my friend who painted them for me. Credibility wise - he is an automotive painter, mixed it according to the instructions, and painted it with a several hundred dollar (thoudsand?) spray gun in a downdraft booth. Looked nice and covered well, but when I went to assemble it, the color on my Magpul FDE furniture does not match the "Magpul FDE" Duracoat I paid for. The actual magpul parts are several shades darker than the "Magpul FDE" duracoat I used for the receiver - I would say a much paler brown.
I now have $150 worth of furniture that does not match $300 worth of receiver parts that I paid duracoat $50 to have match. I am not at all pleased and hopefully by posting here will prevent others from wasting their $.
Duracoat may make a good coating product - just don't plan on it matching anything. Why anyone would name a color "Magpul FDE" when it is not even close to matching that color is beyond me, and very, very upsetting, as I feel I have "ruined" the appearance of my parts - at least to some extent.
Save your money and buy elsewhere. Plenty of other good choices out there for 10-20% as much money.
