The Guz- Ah, I see that others have started using OCW for this
I`ve never tried the M305, but it sounds like a modern version of the M05 New Car Glaze that I like(d) so much...same idea only longer lasting. IMO they oughta have [an independent entity] test it the way Optimum did with the OCW, but I bet most people will just take Meguiar`s word for, well...for whatever they say.
Note that the concern over LSPing to soon/with the wrong stuff is really just about how the paint outgasses/cures. It`s not gonna cause it to fail, and I`ve only heard one report of Clearcoat clouding from waxing too soon (one in all the time we`ve had b/c paint...IMO that says "anomaly"). What can happen, and it`s happened to people here, is that if you do it wrong the paint won`t outgas/cure properly, resulting in it not attaining its max potential hardness, maybe even turning out stupid-soft as per Jet Black.
Even when baked, it can take an incredibly long time for the paint to finish curing and get as hard as it (eventually) will, and sometimes the diffs in hardness during that time are downright amazing.
I myself would fix the buffer trails before I drove the car anywhere (except home from that shop), but that`s just me and if the paint is still really soft it might be easier said than done.
