I primed the other side of the aft spar components today. This new primer, EcoPrime, is terrible to work with, it runs very easily and I had to re-do some of the priming work a couple of times. I would not recommend it but the supplier I used to get the zinc phosphate primer from does not stock it anymore and I've bought half a gallon of the EcoPrime so I guess I'll continue with it, just need to be a lot more careful with it.
