I believe NXT 2.0 has both abrasive and chemical cleaners in it. Chemically, its cleaner has given it the ability to remove tape residue. It also has some very slight abrasive cleaner to allow the permanent removal of very light clear coat scuffing marks, as confirmed by an IPA wipe down. It is the aforementioned cleaning properties that make me question the layerabiity of NXT 2.0.
Don't get me wrong, I think that NXT 2.0 is an acceptable product, due mainly to its filling abilities. I use it exclusively on my daily driver that I don't spend much time polishing. I don't have the time and energy required to rotary polish my daily driver to perfection. I use Ultimate Compound and/or PO203S with the DA to remove visible defects. Any defects that remain or induced by the compound/polishes are simply filled and masked with NXT 2.0.
However, I have never been very satisfied with the durability of NXT 2.0. While NXT 2.0 may be Meguiar's longest lasting LSP, it is probably not the most durable product in the market. For one, I find that two layers of Fuzion Estate wax has longer beading life than two layers of NXT 2.0 under similar washing and weathering conditions.
Truthfully, I am not making any purchasing decisions here. I have both NXT 2.0 and Wolfgang DG 3.0, among other sealants from other competitors. I am just curious as to what Mike Phillips would say regarding the durability of the two sealants. Wolfgang is Autogeek's own line of product, whereas NXT 2.0 is the product of his previous employer.
