Just wondering what everyone is spraying their epoxy with? Hate to spray it with my finishing guns, but the SPI epoxy I use says 1.4-1.5 tip. I have been spraying epoxy with my old 1.8 primer gun.

We've been using the Sagola 3300 with a 1.8 tip for epoxy and 2K primers and the DeVilbiss Finishline with a 1.8 and 2.2 tips for 2K and poly primers. We just put up a Special on the 3300 Pro, check it out at the top of the General Discussion forum.

This is a Vette in 2K shot with the 3300. You can tell it's a pretty smooth and even coating, I had another picture of a black primer job on a Vette done with the 3300 that you could see better but I couldn't find it.

Cool I have the 3300 with the 1.8 tip. Just wondering since the epoxy was thinner if anyone was using a 1.4 with it.

I was using a Sata NR2000 with a 1.4 for epoxy primer and it worked ok but we now use the Sagola 3300 with a 1.8 and the coating is a lot smoother.

I use my 1.4 plus gun for epoxy. Unreduced Kirker is fine. Can't say on SPI.

I will try it with my 3300 tomorrow. I have to epoxy some suspention parts and spray them with semi gloss Centari. Bummer with the SPI is the 30 minute induction period they recommend (so if you guess wrong your stuck wating for more to kick), and that you have to wait 24 hours to spray over it.

I think everything I have with a 1.4 is a top shelf gun and I really dont want to spray epoxy through them. I know I used to have an Astro with a 1.4 somewhere, but I cant find it?!

Also Len, I agree! When I spray primer with the 3300 its almost too nice to sand! I get a lot of "holy shit!" and "what is that stuff you sprayed on there?!" They crap when they find out its regular old primer. I used it today to spray some Centari right out of the can. Looks really good!

Read the SPI TDS again, your statement is incomplete. Don't like induction times? Switch brands.

I will have a look again. And its not my shop to just switch brands. You spray what they get you.

After stripping and bodywork were finished we applied Slick Sand first, guide coated and block sanded with 120 dry then we applied the 2K and wet sanded with 600 wet before painting.

Ive used everything from a 1.8 to a 2.3. The smaller the tip you use the more thinner needed to get it to spray. Bigger is better in this case. Bigger tip = less thinner and more build. I believe there is a thread here somewhere that Len has a new 2.8 tip Sagola and can spray with zero thinner. That would be ideal.

I've been using the 2.8 with the Sagola 3300 Pro with no reducer. You can also use a 2.2 tip with a Finishline but you need need a little reducer to get it to spray properly with that setup.

A used 3300 with the 1.8 is on there but you would need to purchase the 2.8 nozzle kit to go with it. The 3300 Pro will probably go on sale again and you could get a new one on sale.

Yeah I saw that, but a nozzle kit is just about as much as a whole gun. I will probably just wait for the sale and grab one.
