It is very easy to slush cast most vinyls. If you do have a type of
vinyl that either does not adhere well enough or is not viscous
enough to slush cast, then you can always make a back for your mold,
and fill the volume between the front and back with just a shop vac
providing enough vacuum to pull out the bubbles. However, I have
never had a problem slush casting any vinyl part, though to be fair I
have never worked on anything quite as big as a car fender before.

The nice thing about slush casting is that by laying successive
layers, you can get fairly precise control of the thickness of the
parts.
