You should be able to get the info you need from this link.
I have a 25' on a trailer too. I don't want to tell you the way
I'm going to do mine because I'll scare you off - I want to
encourage you. Remember you can spend a lot of time, and
money on a paint job, or not so much. I would recommend
Interlux VC performance epoxi as it is hard paint for a trailered boat. Make sure you familiarize yourself with saftey precautions.
Boat paint can kill you - never sand without total protection.
Never use products with isocyanates without a fresh air in-duction resperator system. A good prep job, and good products
makes the finish. Go for it - you'll be proud of yourself, and take
more pride in your boat, and probable get a better result. Don't
hesitate to ask for more advise. Good luck
