Default Touch Up Gun?

I have a few hard to get into spots on my 77 that I really can't get my full size hvlp gun into to primer They sell a touch up gun but the only size tip that comes with the gun is a 1.0 I am using the ppg NCP 271 primer. It is not a hi build primer. Will it shoot from this gun with the 1.0 tip?

You should not shoot this primer with a 1.0 tip.
According to PPG P-sheet for NCP271 requires 1.4 to 1.6 fluid tip.
A 1.0 will not atomize the primer correctly and it will get very messy, to say the least.
Just a word of caution, You should always read the P-sheets on anything your looking to spray.
These instructions are the bible for any painter.
Attached is the link to the PPG primer/ sealer P-sheets.
I download the PDF's on to my PC then print out the sheet for whatever I am going to spray that day.

Hope this helps
