Do it on your own!!!

They will make the product sounds magical for you. Like you will never have to polish your car again. But that's rubbish!! No products on earth can make that happen.

If you wanna do paint protection on your own. Just making sure the product you are using is sealant based, but not polish based.

You can layer sealant and build up the "clear coating". But polish, you are actually removing thin layers on the clear coating.

Cheers,
