Waterbase in my opinion is far better than solvent as you don't get the same paint reactions or problems.a lot of people don't like using it as its too hard to paint for them and you do have to force dry it with special blowers.it doesn't dry naturally like solvent unless you use a manufacture which use drying solution within the paint.
Ie when checking colour you have to spray the cards out first as waterbase is never the Same colour wet and it is dry.if spraying a silver car when its applied it will go on either a blue or purple ish colour then dry through the coats til it reaches silver and I think it scares many body shops who don't have the skill or knowledge with them.but solvent car paints are illegal now to sell (unless sold as something else) so all body shops are supposed to be voc compliant now using waterbourne paints etc
Its personal choice madman but you should try some one day.cone down ile let you spray some panels in the booth so you can see how it goes.
Plus also you need a special spray gun for waterbase paints.my gun is a Sata chip foose costing me around £700 and I have 2 of them.and that's just for base.for laquer you need another gun.i try to use a differant gun for every application to save contamination.so all in all I have around 7 Sata and devillbiss guns ranging from 300-700 each so it's defo not cheap running a paint shop but in my opinion you have to be up to scratch with today's ins and outs.
Ile get the kettle on for when you come for training buddy
