Is the NXT 2.0 not that great for black cars? Who has used it on their black cars? My cobra is 2 toned Black/ Red so i want a selant/wax that will look good on both.
It does leave a nice finish but I've never gotten it to 'not streak'. It's durability isn't great either. For me synthetics should be long lasting and easy to apply and I find neither is true with NXT. I tried Mother's Synwax and was very impressed. Easiest LSP I've ever had to remove.
If you want a balls out ridiculous finish for black/red, try Pinnacle Souveran. You may not agree with its price but few waxes are better.
On a budget, I've always liked Meguiar's #26 or Mother's Pure (both carnaubas). Probably the best value for money.
