NYmack66:
Here's my 2 cents..
From what I have read you'll most likely need a much smaller tipped spray gun when using the gelcoat/duratec mix. My understanding (since I haven't it yet) is that when mixed 50/50, the Duratec significantly reduces the viscosity of the gelcoat to the point it can be sprayed from a HVLP using a 1.8MM or larger tip. I suspect a if you attempt to spray it form gun you used to apply the gelcoat (4.7 MM) you won't be happy with the results. If you need a gun for this phase of the project let me know and I'll send you the one I recently purchased (HVLP 2.3 MM) if you promise to return it when your finished.
P.S. Your going to need some of acetone to clean the gun after each use.
