OK - I can afford a moisture trap. I've been trying since posting the photos to Google a manual for the Husky sprayer without success. Any idea where to find one?

I guess it would be prudent to get the manual for the compressor as well. I suspect it has some maintenance requirements.

With a different tip, could I do my own sand blasting with this compressor too?

Blasting isn't expensive, but painting is. Maybe to avoid silicosis and to save time, I should just pay to have my frame blasted & then use this rig to do the painting?

What's the learning curve for the paint ***? Last time I painted a frame with spray cans, I had only one sag. How long will it take me to become competent with the air sprayer?
