I have 4 hours on Saturday morning to give the 348 a clean. I recently purchased the full accompaniment of Zymol kit to give car a solid going over at some point in the very near future, however, I realise my 4 hours this Sat is not going to be enough to do this well (esp. as Zymol virgin). Having said that, I have had the car out recently and it has picked up some grime and saltand I want to get this off asap - any suggestions on how best I use the time? Is it worth using any of the Zymol products, or would this be pointless if I am not going to be able to do the whole thing?
