Hey Man great to hear that you have been bitten by the Celica bug. There are a few options,
1 post your request on the VIC forums,
2 do a quicky TAFE course
3 get a load of info/ books from TAFE library
4 get to know an apprentice panel beater/spraypainter, and learn as he learns.
If all else fails give me a PM, as I have repainted a few Celica's up here in Canberra.
