Noticed a big difference after I switched to waterborne primer

Sprayed two quarter panels last month one with old solvent primer and one with waterborne. The waterborne stuff laid down way smoother with less orange peel right out of the gun. Anyone else make that switch and see the same thing?

Waterborne primer does spray differently but it's not really smoother out of the gun. What you're probably seeing is the low VOC solvents evaporate slower so the material stays wet longer and levels out better before it sets up. Solvent primer flashes off fast which can cause that orange peel if you don't have your gun settings dialed in perfect. The real difference is you gotta watch your film build more careful with waterborne because it's easier to apply too heavy and get runs. Make sure you're using the right reducer for your temperature too, that makes a big difference with how it lays down.

The 2k waterborne primer I started using, Wanda 2.1, definitely levels out flatter than my old solvent stuff. It stays wet just long enough to flow out nice but I still get runs if I'm not careful with my coats. You really need to check your reducer and temperature like Thomas said or it can go south quick.
