Clay Bars are pish!

[pacey]

I would add AG Tar Remover before claying better to dissolve the stuff off the best you can rather shear it off.

tried that stuff before didnt think much off it like but the t-cut worked a treat for me like.

A G tar remover is awesome espacially after trying loads of other products first .
Weve had a lot of resurfacing around our area and that stuff has been a god send
