Came across Mers clay bar system on Amazon and seems to be the cheapest i can find it, anyone know if its any good?
Might give it a punt for the price.

Never used it myself but can't see the harm in trying it at that price.

My experience with clay is different types are better for different situations

Meguiars is good but expensive
Bilt hamber is cheap, easy to use but crumbly and not as effective as the megs

Zaino's clay bar system is the best all rounder I've used so far, get lots of clay for the price and lifts a lot of contamination from the paint, well worth a go if you're interested
 
As above get some Bilt Hamber water lubed its cheap and you get a big lump of it and the support of Bilt Hamber.. Bad claying can cause marring (marking) of the paint and creates more work.
Best First use tar Remover (Tardis) then clay saves it clogging up.
 
Cheers guys, decided to give it a go.

Also ordered some autoglym HD wax from amazon as its the cheapest I've ever seen it, £24.35 delivered :clap:
 
I've got the Auto Smart clay kit use it with Reglaze comes up lovely, and not to bad on the price considering the size of the bar
