This is largely up to you and can be decided through whether you want durability, cost effectiveness, non toxic, or some other reasoning. Basically there are alot of options so i will try and broadstroke the main different types of paint you will most often encounter. There are two main groups of paint, oilbase and waterbase paint. There is also water borne but thats another topic. The basic difference in the two or an easy explanation is that water base pai t are going to be thinned and cleaned up with water while oil bvb ase paints use solvents like laquer thinner, butyl, mineral spirits, xylene, and so on. Either choice can be a great choice and the difference, atleast as far as what ive seen is that oil base paint is what you would lean towards if you want a more high gloss finish as opposed to a more matte finish. That being said, these days there are waterborne pai ts that can achieve this look also. Both can be durable and long lasting depending on the quality of paint you purchased. As with anything there is good bad and in between but with paint you pretty much get what you pay for. If you’re looking for the longest lasting blouses most durable finish as far as hardness goes with flexibility then I polyurethane paint is what you will likely won’t. If you just need to cover something and have it look good for a little while before it starts to fade then an enamel paint will likely suits you better. Latex can last for years and years but in general it is going to give you a more dull finish so if that is what you are looking for then latex will do the job.
