I've just sprayed some bits using cellulose.
How soon can I "Tcut" them?
I don't want to wipe all the paint off.
IIRC you have to wait about 2 weeks for the paint to harden properly.
Cheers! 
I do it the next day. It's a lot easier while the paint is still soft!
Don't use T-cut it's got lots of ammonia in and can lead to the paint going prematurely matt.
Auotglym do a paint restorer which is faster and better than t-cut with no ammonia. About £3.50 from Halfrauds.
Use a Farecla rubbing compound. It is what the bodyshops use. I agree TCut can matt the paint and also change its colour with the ammonia. White goes
yellow if you leave tcut on for 24 hrs!

I used t cut until I found the autoglym paint restorer. A lot easier to use than tcut and better results IMO.

It really depends on how much work the paint needs. If you need to remove dirt nibs and reduce orange peel than polishing by hand (with T-Cut or
anything else) will be a long and tiring process.
T-Cut will be OK for just adding shine but anything else really needs doing with a polishing mop.
Either Farecla or 3M products will be suitable.
Years ago, when I was young and (maybe) stupid, I used Brasso to bring up a shine on a motorcycle tank I had painted. It seemed to work really well.
Was this a bad idea?
