Hello everyone. I'am new to painting. I'am looking at this iwata but I'am confused about a couple of things. I want to get the 1.3mm and buy a 1.4mm needle/fluid tip for clears. Can I still use the orange cap or do I need to get the regular silver cap for clears ? Reading iwatas website says this gun is set up for base coats. Should I just buy a different gun just for clears ? Maybe a devilbiss 670 for clears ? Thanks for the help.
