The only issue with HVLP spray guns is that they don’t work with thick paints and require thinned paints for spraying. Due to the presence of air compressor and turbine, there is very less or minimal production of noise from the HVLP spray gun whereas due to the presence of piston for spraying paint in an airless sprayers make it noises.
When dealing with paints, you need to keep in mind that they are made from harsh chemicals which can cause damage to the person eyes or any other body part if gets in contact.
