silicones

I have noticed while reading about different polishes some contain silicones. I have read that these silicones can cause problems with repainting. What are the pros and cons of silicones and why would so many products have them if they cause trouble? Just wondering. Thanks.

Q: Should I Use A Non-Silicone Wax?

A: If your car needs repainting, silicone-based waxes create extra work for the painter. The wax will have to be removed to avoid "fish-eye_ problems in the painting process. The silicone embeds itself into the paint and new paint won't adhere properly.

The use of some silicone does make certain wax formulas easier to spread. There are good silicones and bad silicones. Some are good and necessary to achieve the best finish on a paint surface. It would be naive to avoid silicones altogether.


Take notice that some companies may say that the products

"Contain no HARMFUL silicones"

Notice the word HARMFUL and that they do not say
"Contain NO silicones"

Here is some interesting reading from GE Silicones...

NEVER! won't let it in the door! I've seen the result a couple a times and it is NOT pretty.
 
Actual tests have shown silicone can travel up to a mile and still get the fresh paint...

Believe it or not...

Nasty stuff...
NEVER open a paint shop next to..., or even near a detail shop...
 
Wow i've never heard that one b4. We can acutaly wash our personal vehicls at the shop on the weekends and use our own products silicone or not and never had a problem. Maybee though.
 
Exactly as said before...body shop safe products are silicone and wax free...never let the bad silicone through the door..the water-based ones are not harmful and the products for tires and trim that are sold to bodyshop do have it in them...as it is needed to make the products move easily.

Just think the name Dupont , PPG , and Sikkens are not on wax products....even though I heard that for a very limited time Dupont tried to have a wax with I think it was one of the Nascar's they sposor...didn't work as I here...

While the memory is a little fuzzy, I'm thinking that No. 7 Polish was originally marketed as Dupont No. 7. Almost the same can as today. Dark Green with red lettering. The Dupont was quite prominent in the name. This was sometime in the late 40's or '50's. A Dupont No.7 car wash powder seems to be a distant memory as well. Seems like many of my memories are fuzzy. Even those from last week. :(
 
you're not fuzzy they were polishes and cleaners..no wax... no silicone

back then there were only a few products Old #7 in the green can and a white compound too:eek

then there was simonize system but if you weren't a weight lifter, chances are you couldn't do it right..real pita

and little do people know there was the Original Liquid Glass,
not the stuf fwith a Corvette on the can..it was totally different and really was great for the old finishes..I have an original can and it has a rocket car with the developer and his wife cartooned in and you wouldn't believe the price on the can

How can you determine what is good or bad silicone? It seems wise to stay away from it when possible, but I agree that it would be naive to not use it at all. I may be mistaken but do not several qd contain silicone?
 
to make it simple Ash...good ones are water-based products and water soluable (sp?) usually a milky white...or milky looking if colored

bad ones cause cancer and are not water-soluable

simple as i can think of saying it..
