Hi Detailer's Domain, Last year I purchased an exterior kit from you guys, I actually walked in and you were very nice about letting me to get in to your store although you guys are just online shop. Although I asked a lot of questions and made things clear but it was fall last year when I came. I never get up to the polishing and wax/sealant step and I forgot some of the advice they guy gave me I bought the Adam's Essentials kit. The guy, I believe his name is Dan recommended me to use Meguiar's DA 300 and Menzerna SF 4000 Instead of getting the Adam's Swirl and Haze Remover (16oz) and Adam's Revive Fine Hand Polish (16oz) base on what he saw on my car. I know he told me this once already. But I forgot. Why do I need to use both polishing compound? I was able to tackle majority of the swirl marks and scratches out with Meguiar's DA300. What would the SF4000 add to the result If I use it after the DA300? Thanks all the help, Matt
