Surface Cleaning Prep
I use this prior to applying coatings and sometimes up sell with this before a wax. Cleans the surface really well. Doesn't remove any defects so don't buy for that purpose. It just cleans the surface really well so you can have a clean surface for a sealant or coating.
Don't use much product. One dime size amount for a 2'x4' or so area.

The best paint cleaner, hands down
I've used lots and lots of paint cleaners, all have done the job, but almost all of them seem to leave something behind, like a glaze or fillers. DP Prep Polish is different, it leave the paint surgically clean, perfect for applying coatings or your other favorite LSP's. I've used DP Prep when applying DP Paint Coating, CQ UK and Opti Coat and never had issues with bonding. It's the ideal paint cleaner for coatings.

A bottle goes a long way, the product runs thin so it spreads far, so you'll use minimal product. I'd opt for the 32oz, more bang for your buck. This really pulls dirt out of your paint, won't correct marring, but surely will clean better than anything else you'll use.
ProsPrice, application, cleaning ability.
