Was reading up on tip sizes and some think that a 1.3 tip might atomize way to good and thus be a problem. Sounds like a 1.4 for shooting the base coats and clears would be a better choice.

For spraying primer that you can block sand would it be better to have a 1.5 tip or something more like a 2.0? reading that some use a 1.5 for primer but have also read where you need something a lot bigger like a 1.8 to 2.0...

A lot of choices out there.
