GT85 I use for spraying on all the moving parts such as hinge pins and Driveshafts, keeps them lubed and disperses any water that might be caught in there.
I also give my bodyshell and wing a good coating and a quick wipe and it keeps most of the mud and grass from sticking during a run and makes it come off easier when cleaning. Don't go to ott on it though otherwise it will be like marshalling a wet fish.
I usually spray a bit on my cleaning brush as well and makes your driveshafts and plastic parts look like new.
