Removing LP Paint from Hull and Repainting - Advice ?

Looking to purchase a nice Catalina 38; however, hull needs maintenance as LP paint is starting to peel- 12 years on?
How to refinish?
Is it going to kill my budget? Which is based mostly on Manuel Labor.
Thanks very much!

Linear Polyurethane...Awlgrip, Sterling etc.

The paint was not applied correctly. It should not be delaminating after only 12 years. Given this, it appears that the old paint will need to be removed. You do not want to put good paint over bad paint, especially with something as expensive as a spray on LPU paint job.

Have the paint expert at the boat yard take a close look for a final decision.

Thanks David for your reply. Is this a reasonable job to tackle with proper prep, considering labor savings? We're not afraid if elbow grease and would hire sanding help for sure.
We spoke to a boatyard and he advised also that the prep was most likely inadequate.
All that being said-any good links on technical advice for paint and prep?

If you're going to sand it yourself get a couple PC 1/2 sheet sanders and someone to rub your shoulders each evening. Hard work but do-able. Most likely you'll have to go to the original gel coat. Good luck and have fun.

h2loca, if the paint is peeling or flaking, it's not properly attached to the substrate. I would chemically strip it completely off and neutralize the surface afterwards. The application of an epoxy sanding primer would follow. Then I would sand it fair prior to filling any pinholes or body damage with an epoxy fairing compound. Once it was completely faired (spray a bit of polyurethane primer over the bodywork to check it) you would be ready to apply the new LPU. When setting your budget, remember that a good repaint of a C-38 would run you anywhere from 5K to 9K depending on location and the paint quality.

If your yard allows it, hire some day laborers with sizable deltoids and triceps to do the hard work. Otherwise, tell the yard they are your amigos coming to help out.

You might be able to rent the half-sheet sanders.
