Hi Ken,

I agree with Lee.  We are using acrylic for some products and silicone for
some others.  It was strongly suggested to us to use silicone coating with
the same gun all the time.  It seems that silicone even properly clean is
likely to leave some kind of residue that will prevent getting good quality
with other coatings.  I think it was someone at M.G. Chemicals that told
us that.  Be careful before you switch coatings in the same gun...
