Porsche 944 or not, this is a great read. It is a two part how-to.
Personally I don’t have the time and have been researching a place to do the New Beetle. I have done this routine in the past but right now it just need doing. We have a ton of rail dust on top of the usually birds, trees, etc. A claybar is #1 on anyones list. If you’ve used one you know it will make your car a smooth as a baby’s butt!
