Looks awesome! I was wondering the same thing. I recently polished out a black car and it's wearing Wolfgang Deep Gloss Paint Sealant w/ Souveran. I am planning a trip back to the clients house to strip LSP's, fix minor swirling, and coat with the same combo you used. Thanks for the picture! I will show him tomorrow to see if he's up for it.
Great look- Souveran + MPL. I really enjoy using MPL...easy on/easy off. I top it with Fuzion.
As far as comparing it to DP PC...it's close, but MPL is a little slicker and a little easier to use, IMO. I cannot comment on durability....both are good.
