I'm not a member of that board, so I can't see your pics. Depending on how bad the key marks are, you may be able to have them fixed as opposed to having the panel repainted.
Definitely get a hold of the factory touch up paints that match your paint codes for the affected areas. There are many touch up paint systems on the market and some of them work OK, but most don't give you the flawless finish that you once had. With the right prep work, paint and finish work, you can often have your flawless finish back without repainting the entire panel and it will often last for years. It's a very time consuming process that's better left to someone experienced, but it's not beyond a good detailer to fix the scratch and get your car back to looking flawless.
If the key marks are on the hood or a panel that's exposed to lots of sun / uv, then there may be slight issues down the road with any spot type of repair. The problem with repairing a key mark or something like that with 2 stage paint is there's a greater possibility that years down the road the repair may get a slight ring around it due to the clear coat being thinner at the edges of the repair. The best repair of course is to strip the panel up to a natural line and repaint it, but these kinds of repairs can get expensive.
