Just make sure you have a base coat when you repaint it because sometimes undercoats will actually show up, so if it's already camo'ed then prime it with black and put an overcoat. That's the "lazy mans way".

The better way would be to strip it off with something SUPER soft, not like a kiwi cloth but something that would abrade the paint but not destroy it.

When you paint, primers do two things, make the overcoat stick better AND they prevent any under colours from showing.

ie. you want to paint your car a new colour, well you would probably want to do a neutral primer coat to make sure the colour underneath doesn't show through (unless that's the effect you want).

Also it's better to do a few light primer coats than a heavy one.

One more thing, white primer is better for lighter colours and black primer better for darker colours, so if you're doing a dark colour like forest green, earth brown, etc. then best bet is a black primer, whereas if you want to make your gun like that Hello Kitty M4 then white is probably a better choice.
