Digital BW, The Print

Bill,

That is interesting. There was talk last summer about using automotive paint
spray systems for coating prints. You are the first I have heard from that
actually tried it with good results.

One of this issues with any application method, especially brush and quality
spray, is that use of the particular tools is a skill you have to spend some
time mastering. People have to realize that there is a learning curve to
this. Those who are experienced with a particular application tool may not
know just how difficult or impossible it may be for a beginner to get good
results.

I would be cautious with non-art grade coatings after seeing how some of the
stuff I tried yellowed on me. I am not familiar with the Deft. Is it an
acrylic or a polyurethane or something else?

Are you spraying in a spray booth? How do you control fumes, dust, etc.?
