Gun advice for primer on small area.

I've been trying to apply my HOK KD3000 epoxy primer as a medium build surfacer with a larger airbrush. The parts i'm spraying are small, about the size of a roll of quarters so I'm not mixing up a ton of material at a time. I'm needing a good smooth surface though and I've been getting some orange peel and dry spray out of the airbrush.
I was thinking of picking up a small detail gun just for applying primer but I had a couple questions.
1. HOK recommends up to a 1.7 tip in their tech sheet for gunsetup. What tip size size would be equivalent in a mini detail gun?

2. Would a detail gun be a better solution or something like a full size gun with small cup be better? Again I'm spraying small amounts of primer at a time. Maybe 1 ounce.

I've had good results with a cheap HF detail gun for shooting SPI epoxy. I, too, sometimes spray small amounts and buy pint and/or half-pint mix cups for these occasions...

Thanks bud. Ya I usually spray around 1 ounce or less. I found TCP Global carries a small detail gun with a 1.2 tip as well.

I use the HF detail gun on occasion, sounds like You may have to use some reducer. LOL, the tiny little detail gun costs me three times as much as that big gun (well worth 30.00) it has worked great for me for 2 yrs at the shop, so far nothings fallin off I really like it. Every time I forget to clean it when Im done I say I'll toss it and get another one but I never did that epoxy can be a mother to get out when its all dried up in there. Its taken the abuse very well at the shop. Primer and paint may need a little reduction sometimes

Thanks Bodyman. I am reducing out the primer to medium build or as a sealer and the airbrush will spray it just not a good wet coat like i'm wanting. For 30 bucks and free shipping it can't hurt to try a detail gun. If i have to go to a larger gun i will but I really think that is overkill for me.

You can get it wetter by adjusting the fan The smaller the fan the more comes out, You wont get much primer out of the gun with a full fan, play with it a little you'll get it.
