Primer report: Stewart Systems EkoPoxy

[GPV]

Thanks for the input guys. I'm going to have another go at it this weekend and will fiddle with the paint and mixture settings. I suspect my air pressure was too high as quite a few people have now suggested it is the first thing to check!

Thanks again,

Greg

I shot some other parts using the 1.8 mm tip and got a smoother finish. My overall impression is that Ekopoxy is a good product, as long as you can put up with the mixing hassles and can spray it within the humidity and temperature limits.

Also, I really like the PPS cup system. Although an aftermarket system, and not cheap, it's worth getting.

The primer is like milk, no mixing, you can save what you don't use for intermittent spray sessions.

Larry what manufacturer of white single component primer and urethane grey did you use?

[Larry DeCamp]

The single component primer with Ekopoly grey 2k finish has been very scratch resistant.
However, as I have warned many times, you must completely cover the primer with 2K material . ALL exposed edges or wicking paths TO the primer for solvents or mogas WILL soften and blister the finish coat.
