I use meguiars body shampoo 1st (as i think it foams much better than autoglym)
then autoglym super resin polish its the bollocks
and ive just brought some meguiars wax im going to try it out today so cant comment on that yet but i looks good
thats my experience and i can tell you it really does the job very well halfords have got 241 on autoglym at the moment
I also brought a autoglym calaformia blade for cleaning off water after washing, i would highly reccoment 1 of these as they makes it ten times quicker and the water doesnt get time to dry like it can with a chamois.
1 final tip,j instead of buying glass polish just use normal super resin does exactly the same job and saves getting two polishes out. I personally stay away from the likes of fast glass cleaner as it can smear, polish is completele smear free.
*EDIT* Just read that yours is black auto glym do a specific polish for dark colours not sure of the exact name sure someone will know, a friend of mine uses it on his rst and it look mint!
hope this helps
