I have noticed alot of people talking about the actual painting process, but IMHO, the preparation process is key to the whole thing coming off (no pun intended)!
Preperation: Last time I did it (R22), I didn't prep properly and all the paint flew off mid-flight....man, what a fright!!
Second time round, I spent considerable time preparing, stripping back the old paint with a mixture of Coke & Sellys Heavy Duty Strip All (c). The mix was roughly 50/50. Let the mix work for about 2 hours....good time for a beer or 2.
Application: I sprayed first time round, but used a hand roller the second time. (Little tip: be sure to let the top dry before flipping over to do the underside. Again, took me a few goes to get this right!).
Once she's all dry, bolt those bad boys back on and Bob's your Auntie!
You may get a few vibs for the first few hours of flight, but trust me, if you got it right, they should be all gone by 10 hours after the paitn job (this is a great check to ensure you got it right!!).
Good luck!!
