Hova Flight Services Winter Haven, Fl.

I happened by pure chance to get the grand tour with the owner while departing from Sun N Fun this year.
He is a purely a paint shop and it shows in the work I was able to see. They do have A&Ps to do the mechanic work but have talented prep and painters on the team. All flight controls are removed for painting. This allows for the paint scheme to reach viewable areas when the controls are moved.
He does use as environmentaly friendly products as possible. We are talking paint here.
He can take a solid aircraft disassemble, strip prep and paint in around 10 working days once at the facility. This does mean it is an airworthy plane with no hidden damage found when the vail of paint is removed. He has refused service to planes that show up and will likely be a hanger queen if he starts work.
I'm considering my C170 paint removal to polished with them. They have a great system for paint removal. It will leave me an entire winter to polish it at home.
My friend is on his list for his Bonanza next spring. A decent price for the time it takes to turn it back out.
Again if you start with an airworthy plane with no other issues you get the plane back quickly. As of last spring he is about 8 months out for scheduling.
