Do it all the time.So what I'm gathering from the replies is I can use the 2.5 but may need to cut back on the fluid delivery?
Do it all the time.
once you get past the first couple of panels and realize that it isn't Slick Sand so you need to turn the fluid control in a bit and move the gun faster. Oops.
I also have the iwata airgunsa 2.0. Wide open for poly and dial it back for 2k. It's a pretty good gun for 120 bucks if I remember correctly1.4 tip for epoxy works perfect.
I used a 1.8 for 2k for years but can't get a rebuild kit for that gun anymore. Bought a Air Gunsa 2.0 that I now use for 2k and polyester primer.
Just curious why you recommend not spraying 2k until filler work is done? Is it because its porous?The condition of the surface after epoxy dictates the next step. It could need anything from filler to just a couple more coats of epoxy. My advice is do not spray a 2K product until the surface does not need any more filler work. In other words, all the low spots and pinholes are filled before 2K. SPI makes 3 different 2K primers. Regular build, high build and Turbo. I use Turbo myself because of the versatility, availability of white, faster through dry, and ease of sanding. It can be mixed 4:1 to 4:1:1 depending on the fill you need. I've sprayed it mixed 4:1:1 with a 1.3 tip, or even a 1.0 touch up gun on small spots. Mixed 4:1, it needs a 1.8 or bigger tip and fills similar to the high build.
ThanksIt is one of the most common mistakes made by someone without a lot of experience. They want to get to the primer stage way before it is ready to feel like they are making progress. Filler is not made to go over 2K. Some polyester putties and glazes are ok, but they are made to be applied in small spots and very thin coats. 2K should not be used as filler, which is what happens a lot, if it is sprayed before the filler work is ready. What works well is spraying epoxy wet over filler and fixing all the imperfections before any 2K.

You're not wrong lolNow I see how the astronaut's panels end up so perfect. The amount of blocking it takes to get the runs out assures the panel is straight.
