Some advantages to this are no mixing drops, no wasting un-used product, available locally-if not, no expensive z-$hipping costs, etc .... I think we've hit a nerve ... again ... http://autopia.org/forum/showthread.php?t=9046&highlight=duragloss ...

I used the 111 on our white pickup last fall without the 601. I used the 601 on one small section. With white it was difficult to tell if the 601 improved gloss. What is interesting is that both 601 and ZFX contain aliphatic hydrocarbons-whatever that means(I'm not claiming that those aliphatic hydrocarbons are exactly the same tho).
