Has anybody used this product from Finsih First?

 

Finish First and Liquid Glass are polymer sealers (and IMHO the same product packaged differently)that adhere to themselves (more coats the better) I use Liquid Glass as my paint sealer and also on my wheels. I don't think you need a seperate product. I also top it with a good carnuba.

I use the Liqui-Tech products with excellent results. Using the wheel protector on the S2000 has made brake dust clean up easy and fast. I recommend it.
