I know there is a debate (or maybe not so much of a debate
) as to how well Z5 fills swirls. Z5 filled my swirls, but I was told this was because they were the light.
Anyrate, I'm wondering if anyone can explain how polymer sealants like Z5, and NXT, fill swirl marks?
What's the difference between Z2 and Z5, how come one fills swirls (if they're light) and the other one doesn't?
And finally, is there a difference in durability for sealants that fill swirls versus sealants that do not fill swirls?
