Bottom Painting a Powder Coated Aluminum Hull

[tmal2]

I've decided to purchase a brand new Highfield 290 Classic which has a powder coated aluminum hull. The boat will be staying in the water for about 5 months out of the year so I'm looking to bottom paint it. I know a copper free paint must be used but I have no idea what kind of prep work needs to be done to paint over powder coating. If you've done this before I'd love to hear which products you used and what the process was,

Thanks

just mask a line where you want to paint to then flat the area to be painted with p400, panel wipe. fresh masking off you go
