I have used an off-the-shelf product on the vinyl in my previous vehicles, however, I have found that when I apply this product to my dash area, it appears to cause fogging on my windscreen – why is this?
The product you are using may contain high quantities of silicone. This can sometimes vapourise when the cabin of the vehicle gets very hot. This can result in fogging on glass which is close to the area where the product has been applied. MotorOne High Performance Vinyl Conditioner is a silicone-free formula.
