Vinyl and Trim Dressing is great for all plastics, vinyl and rubber surfaces
It can be used on the exterior, interior and engine bays.
 
Directions of use:
for engine bays wash the engine bay first then liberally spray the product on to the surfaces you want to protect with the dressing
 
tyres - clean your tyres using APC and then spray the dressing directly on to the surface or use a tyre dressing applicator 
 
exterior and interior plastics - spray into an applicator or microfibre cloth and wipe over the surface
buff off any remaining residue
