Auto body repair & detailing: How to spray stonechip?, spraygun, splutter

Question
Sir,
Please may you advise me on how to spray 'stonechip' coating on my vehicle's load bed? I would like to know if it is possible to thin stonechip, and if so, at what ratio. Also what pressure to spray with. I have heard that a special 'splutter nozzle' is required for the spraygun - what is this?  Any advice would be appreciated.
thank you

Answer
I would roller paint aftermarket chip guard on my truck bed. ask you supplier on how to apply and how to reduce their product. I have never heard of a splutter nozzle. Sounds like somone is trying to sell you something you dont need?
       Hope this helps
