Wet vs. dry blasting

I have been asked to provide advice on the advantages or disadvantages of wet blasting versus dry blasting using glass beads in machining. Has a case study been published or is information available that offers this information? Recognizing that resource recovery or pollution prevention must be the most important consideration. What would be your recommendation?

Wet Blasting Method of Surface Preparation is recommended in the areas of Fire Hazard (Eg.Live Facility- Production Area).

We build large work boats. Because of environmental issues we always wet blast. An average of 500 Sq/Mts per vessel. I's a bit slower but much better finish … "Wet is best" … oh and size matters … use a big pot 250psi @ 1200 CFM
