ok just to clear this up. i use a big gun to shoot epoxy BUT i only shoot one coat at a time and let it cure at least 24 hrs in the summer. longer when it is cold or i heat the booth. i do this because i block each coat and want some mil there to sand .
if you plan to shoot several coat at a time DO NOT use the 2.3 i use (which i turn down some ) . you are asking for trouble if you do. use a 1.4 like barry recommends.i am a dinosaur and have my own ways of doing things . i push flash and cure to the max . just wanted to clear this up. had a call from someone who was going to use the big gun and put 3 coats on in one day while it was cool. not a good idea. :(

just food for thought and worth exactly what you paid fer it .
 
Blocking SPI Epoxy is like shooting a product with its own guide coat already built in. I can see exactly why you do it the way you do Shine.

Good info. Thanks for posting before I made a mistake.
 
I have a 2.0 tip gun from northern tool just sitting around at work. Might just use it for epoxy & skip using evercoat g-2 again if I can help it.
 
Being kinda old school also, I would guess you prime fast too? kinda with a "get her done" attitude each pass I do is faster then if I was clearing. My gun has a 1.8 tip and can dump I can only imagine the fluid comming from a 2.3.
 
I spray the epoxy with a 1.8 tip, typically do 2 coats and let it sit for 2 days before sanding.. That formula has worked rather well for me.

I always block sand it before continuing.
 
just wanted to put this out there . couple of guys have tried to hammer it and ended up with craters .
 
May as well ask a question about epoxy pot life here. Since it requires a little patience on dry time, may be breaking up some sanding & spraying into more sections rather than spraying all at one time & having to wait. Also have to get used to induction time after mixing.

Pot life is listed as 70 to 120 hours in sealed container, depending on temp , etc of course. So is there an average safe time range to leave in a gun before respraying, or having to empty into a sealed container.

Trying to learn here, never really used much epoxy primers before. I like my work to shine, pun intended.
 
This depends a lot on how long the epoxy has induced-you'll notice the solids settle quicker if it hasn't induced very long. I'll typically dump it into a mix cup between coats and put a little reducer in the gun.
 
I agree with Bob. I don't leave it in my gun I will leave mine in a can until I'm ready. I don't mix until I'm getting ready to use it, while it is inducing I will be doing final prep and mask for the intended area and only mix what I intend to use for the moment. If I decide I need more I will mix more and wait the time doing something else or take a break for a little bit.
 
i use a vaper 2.3 . i induce overnight . anytime i shoot primers i use my bottle to rinse the head between coats.
 
Kinda thought it wouldn't be good to leave in a gun for too long.

Shine, you find it works much better​ to mix a batch of primer the evening before use?
 
you wont be able to run it wide open. set it up with thinner. start with the fluid in the middle and adjust from there. i run about 3 turns out and around 30lbs of air.if you get craters back out a little. i double coat. med pass down the panel then back up. good luck with it .
