    2nd Gen Addict, Are you telling us that we can go to any Auto Paint Distributor
    and tell them to mix there brand of Epoxy to match a PANTONE 490 chip/sample
    and they would know what we were wanting and how to do it..........

    Myself and Steve Neuer are advocating the use of SPI primer that is sold direct
    and shipped to or door and that's why Steve's hard work is so important
    to the rest of us SPI users.

    Okay, I'll do my best to share my insight on why I mix the way I do.

    First, the only purpose of using a gram scale when mixing the black-to-red-to-flattener is for consistency. therefore, the more accurate the mix, the more likely you are to get two different batches to provide the same finished product appearance. keep in mind, 0.1 gram = 0.0035 oz....a minute amount, so while using the eye-ball scale mixing a quart or more might be fine, when mixing small batches there is greater probability for error. I was borrowing a friend's digital paint scale and when he needed it back for a while, I just went out and bought my own. Found a nice Mettler-Toledo unit used on eBay for about $100. Would a digital scale with 1.0 gram resolution be okay?...probably, but the higher the resolution, the better the match. Also, I searched but could not find a "cheap" digital scale with a range up to approx. 6 lbs. (2.72 Kg). If you don't want to invest in a gram scale, I suggest taking the black, red and flattener to an auto body shop, pay them a few bucks and have them mix up a gallon or so, (depending on how much you intend to consume), in advance.

    As for mixing, I'll use some examples. First to get the my red oxide color, add 8% black to the red oxide. (Ex: 100 gr of Red oxide x .08 = 8 gr of black for a total of 108 gr of material). After the color is determined, then create the desired gloss by adding 5% flattener. (Ex: 108 gr x .05 = 5.4 gr of flattener for a total material of 113.4 gr). Therefore, by starting with 100 gr of Red oxide, the finished mix, (less activator), is 113.4 gr of material. Then add the activator (1:1 mix with material), thin to your desired viscosity and shoot.

    Hope this helps.

    Pantone is an international standard used frequently in the printing industry. A paint supply shop can use it to do accurate matches if they have a device called a color colorimeter like this:

    I use the SPI products as well and will be carefully scrutinizing Steve's recommendations someday and will probably spend endless hours adjusting them until I arrive back to his settings and then just spray the damn thing.

    Steve, This thread or parts of it need to made a "stickie" but given how few people
    on nasty care about true restoration I hope those interested find this thread...

    Was your 5% Flattner only a suggestion or is that what youve found to be appealing
    to your eye versus the red/black formula straight outa the can ????
