Penetrol dilemma

Well i am using it to spray a protective coat underneath and inside the body etc, the paint quailty is crap on the latest models.

Thanks for the info

The rust one will work well for that

Try the paint one if you have problems getting a smooth finish with oil based paint.

An undercoat of ESP and a small amount in the paint helps it to flow evenly over surfaces and adheres to surfaces much better than just ordinary paint.
