Can I spray epoxy primer with these tips?

[k72nova]

I went and bought a DeVilbiss, Startingline kit and plan on spraying my 72 Nova with SPI black epoxy primer, the car is down to bare metal. I have the primer and the gun on hand and the car is in bare metal, I had planned on priming it either today or tomorrow depending on the weather... The problem is that the kit I bought said that it came with 1.0, 1.3, and 1.5 tip, and needle. Unfortunately it did not come with the 1.5 but a 1.8 instead. Am I able to spray epoxy primer with either the 1.3 or 1.8? Like I said the car is down to bare metal so this will be the initial sealing coat for the metal.

I love the 1.8 for epoxy, so yes, use it.
Works real good.
you could use the 1.3 if you reduce it a little,
but the 1.8 is my no.1 choice.

Cool thanks! Do you have any advice on using a 1.8 tip with this stuff? This is my first go painting a project. I've got a few practice panels laying around to test on and I've read the "Paint Gun Adjust" by Barry but any other advice is always welcome.
