Poly primer problem.

So today i used some polyester prime from car-system. but it wasnt spraying out smooth or fast at all.. my gun has a 2.2 tip and i was told it should be plenty. I didnt strain the primer only because of how thick it is.. now im not new to autobody at all. but i couldnt figure out how to get this stuff to spray good.. and i dont even think you can strain this stuff?

It is going spray quite heavy, with texture. But if it is REALLY rough and dry, you may have thin it a little. I don't know that brand at all that you are using, but some have a recommendation of up to 5% lacquer thinner, or "compliant reducer" which is largely acetone.

Also check your air vent.

PPG's Omni MX241 says to use 10% acetone to thin.

All products should be strained, if there any small clumps of unmixed product they will partially clog the fluid tip and ruin sprayability. Besides, you don't want them unmixed non catalyzed clumps to end up on your car. Strain everything that goes in your gun from now on.

I have to say, I have never strained my polyester primer, well, not after the first time I tried.

It is Soooooooooo thick it would cure before it got thru.

No filter is going to stop "unmixed" anything so that is out, honestly, I don't see the need. You not going to spray it and leave it, it MUST be sanded, I don't know, I don't see the need.

you probably already did this but if your using a gravity feed and the stuff wont go through a paint strainer then it wont pass through the gun filter either. be sure and remove that.

I've never had any problems straining polyester primers. I don't load a gun with anything that hasn't been strained.

I must admit that I strain everything but polyester primer (Omni) that I used (just one time) was unstrainable. Even when using my high build primer (Nexa p-565-888) it is slooooow going through the strainer. I would be interested in knowing if you have reduced the polyester. I DO know that you are not using regular paint strainers(can't remember what size mesh mine are). We use the 3-M PPS system(P/N 16000) and we had to remove the built in strainers to get the polyester to come out and they are the same(size) as the PPG strainers.
