Does anyone have any experience (other than flat out guessing based on
advertising!) if the supposedly "high end" garage epoxies would be
much better than the 2-part epoxies such as Rustoleum EpoxyShield?
They have companies that will come in and do the floor for you,
hinting that they use some special epoxy that's better than anything
you could apply yourself. Or there are some DIY sites that advertise
epoxy that's "better" than store-bought. But the Rustoleum et al are
2-part epoxies and not cheap themselves, so they must be competitive.
Or not?

Take a look at Progressive Epoxy Polymers
