If you don't have time for a full rebuild all the time and have access to a good airline, most rally cars break into main parts from the chassis, normally front end gearboxes complete with wishbones etc, centre diff then rear gearbox with wishbones etc, radio tray,Engine pipe tank all together save pulling pipes off and risking dirt in the system. and chassis, then get busy with the GT85 or WD40 a paint brush, stiff brush, tooth brush and the airline normally get a mint looking car within an hour or so
Normally what I used to do between club racing, but as has been said always pays to do a full rebuild say every third time as it's good to give everything a check over (depending on how often you get to do a full days racing)
One ting I always used to see club racing was people who stripped there car every week 9 times out of 10 ether broke in practice or in the 1st heat normally because they hadn't done something back up

then they spent a fortune on screws as they constantly stripped the heads out of them unscrew then screwing them back up with the trusty electric screwdriver
