Why is silicone in QD bad?

[Dave N]

I've read in a few posts here that people prefer a QD without silicone. Why is this? Will it hurt the paint?

I have some Final Inspection on order, but right now I'm using regular Meguiar's QD. I think I someone said this contains silicone...

Thanks,
Dave.

Silicone is bad for paint shops, as it inhibits paint to stick on the car. A bad thing if you're running a paint shop; fairly irrelevant if you're a weekend warrior detailer like most of us.

Body and paint shops hate the stuff. Fact is, if someone is detailing a car 1/4 mile away from a paint shop, and it's a windy day, it's been known that silicone from detailing products can travel airborne that far and cause fisheyes in paint!I've painted quite a few cars, and have friends in the business, and it's a pain in the butt to have to use additives in paint to prevent this from occurring.Also affects the paints durability. For the car owner, it's not a problem.( till you have a accident and need paintwork lol). DAN H

Why I would avoid silicone containing quick detailers is the dust factor. It leaves a greasy finish that is a dust magnet.

It also clouds on dark colors. It can also go through the paint all the way to the metal.

is not a bad thing - it's the TYPE of silicone that can be bad.

Some of the inexpensive rubber and vinyl protectants use a low grade of silicone that isn't easily removed by paint preps - these are the types of silicones referred to by body shop folks as being "bad".

Please don't confuse the types used in rubber dressings with the types used in paint detailers - they are 2 different animals.

And, the type of silicone used by Bo Derek back 20 years ago wasn't so bad either.......

If silicon does cloud dark paint, is there anything that can be done to remove it?

Which detailers do you think have no silicone? I bet you would be surprised if you got an MSDS
