What prep is necessary for painting

[USKEW]

I'm going to repaint my jon back to original jon boat green. Was going to by the Parker's duck boat paint in the hunter green. What should I do to prep? If the original paint from the mfg is not really coming off, do I really have to strip? Do I need to use primer? Can I just pressure wash and degrease, then paint over?

Is there a better paint to be used other than the Parkers? Here is a pic of the boat and condition of the paint. Thanks.

PS - what's the best way to remove the old decals?

Clean it, sand it with 100,120 grit, degrease, prime it and then paint, it will last a lot longer. Just my opinion, others will probably give other advise. Don't know anything about Parker's, Interlux is the best paint I know of, but a lot more expensive. Decals can be removed with hair dryer or heat gun, (be very careful with heat gun).
