Painting process - any critiques or suggestions?

I'm getting prepared to paint my 2011 EZGO. I don't have access to an air gun, so I'll be using rattle cans. I think I have a handle on things, a big thanks to Master and the sticky post about plastic prep! Just to make sure I'm not about to do something dumb, how does this look:

-Scuff body; remove shine only

Burgundy/maroon scotchbrite or 240-400 grit dry sand

-Wipe down with wax and grease remover

On with one rag, off with a fresh one

-Bodywork (if needed)

Polyester based finishing putty

Sand with 240-320 grit dry

Wax and grease remover again

-Adhesion promoter (1 coat)

-Primer (2-3 coats)

Usually 15-20 mins between coats

24-36 hours after final coat

-Sand

240 if early coat, 400-600 grit if final coat

-Clean with tack cloth

-Color (2-3 coats)

Usually 15-20 mins between coats

24-36 hours after final coat

-Clean with tack cloth

-Clear (2-3 coats)

Usually 15-20 mins between coats

Wait 24-36 hours

-1500-2000 wet sand

-Buff with cutting compound
