Poorboys are generally really good, I've not used Dodo much though. I've used a Meguiars G220 as a DA Polisher on 3 cars now, worked absolutely spot on and much less risky than using an orbital or similar. Claying is cheap and simple to do and has incredible results on your paintwork, would recommend it to anyone. Poorboys degreaser is good, get a decent foaming head and bottle and it does a top job, can be diluted up to 100:1 too so lasts ages. Tyre shine is generally the same, I use the Meguiars stuff you can buy anywhere that is purple, smells good enough to drink and however much you put on decides how shiny the tyres will be. Lasts bloody ages.
