Right now I do not have a DA but plan to get one eventually. For hand work now and DA work later which do you like better for a step after clay Meg151 or BF SRC finishing polish? If the vehicle is so messed up it needs more I will look into Meg105/205 or something but I may not want to ever do anything thats bad enough to need anymore. I will follow these with either BF GEP or go straight to WDAFPP, 845, or FK1000p which ever I am using on the vehicle. I have the GEP, WDAFPP, and 845 already and plan to get some 1000p to try(not sure if it is any better than what I have already or not). I am just a hobbiest and friend and family guy. Todd threw MEnz powerfinish in the mix as something to think about. I have FK425, OCW, Aquawax, and two bottles of UWW+ to use also. Any advice on other products I might want to try and things I have already from above to use together and not to.
