anyone know what actual polymers are being used in all the new synthetic sealants?



my girlfriend is a polymer chemist and I was thinking it might be fun to do some garage chemistry and see if we can work up a good homebrew sealant? :)
 
A lot of them use some sort of silicone polymers; PDMS (Polydimethylsiloxane) is a popular one. There's a lot more that goes into them other than the polymers themselves though...
 
right, but once you know what you're looking to get on the car's surface, the rest is just a matter of engineering.



I'll have to take a look ad PDMS



and as for "acrylic polymers", that could be quite a few things.

A LOT of engineering. Professional manufacturers hire a whole team of chemists who already know what types of polymers to start with, but it is the rest of the chemical engineering that requires a lot of time, money and expertise.
