finishing metalic body paints

I have read a few things about how you cant sand metallic paints as it takes away the shine and metallic flecks. I want to paint my HKS TUNED WRX metallic silver but this is kind of putting me off.
Could some one please give me a simple out line of how to finish a metallic paint successfully eg sanding,wet sanding, cutting compound polish, clear coats?
Im clear on how to prepare it eg sanding priming but just a little misty on the finish.
Thanks

i would use meguirs quick wax, and polish it. or you can clear coat. me i am still learning things i never knew like how much clear coat and do, and polishs

as far as wet sanding metalic finsihs, never heard that you cant do it

I've painted my Focus with metallic paint and I used the same method as per any other paint and got the best finish ever! I don't think sandind takes the sine away. Well, it didn't on my case! :D
My painting process is:
1: wetsand the body with 1500 grit
2: 3 mistcoats of primer and 1 heavier coat
3: wetsand the primer with 2000 grit
4: 2 mist coats of paint (metallic or not)
5: 2 wetcotas of paint
6: compound as usual
7: wax as usual

heres my new method i just started with

1. do all body work
2. sand
3. wet sand 900 grit
4. primer light coat
5. final primer
6. 2000 grit sand primer
7. 1 light coat of paint
8. a final coat ofpaint
9. clear coat
10. polish and wax it

i found this works great on the bigger scale models, i used to do 1/43 scale and hard to work with

i probably practice the simplest method when i did my silver impreza which the finish came out imo real nice.
1. primer
2. couple coats of testors metallic silver
3. clear coat
4. polish out

Thanks heaps guys the info is very helpful. I cant wait to give it a crack.i just gotta go out and get the paints now but i also have to set up a half decent spray booth because i want it to be perfect.
Thanks again
