Mitch, I use wax and grease remover from Supercheap. What is the chemical name for this? is it shellite.

Thats what im using, wax & grease remover from Supercheap. Prepsol is just another brand name i think for the same stuff so thats what i refer to it as. So the Supercheap wax & grease remover IS Prepsol far as im concerned.. its the same stuff as the "Prepsol" brand i used years ago when working with my brother spraypainting/panelbeating cars.

Anyway... back on topic, update coming tonight
