A quote from April 1, 2004 (Vol 30 #7) Practical Sailor (I've never
personally used the stuff):
"Gelcoat Restoration: Back From the Dead"
"We used hull restorers from Vertglas, Poli-Glow, and New Glass-2 to revive
a beaten and battered powerboat.
Their thin acrylic film coatings bring a high-gloss sheen to a gelcoat.
They do require meticulous preparation and application, and can be tough to
remove. Product tested this time were: Poli Glow, Vertglas and New Glass-2."
"These wipe-on coatings consist of resins of higher molecular weight that
provide harder and more durable film than can be achieved with wax. The
products tested consist of water-based emulsions of acrylic or
acrylic/urethane resins. Their resins are in the form of tiny droplets that
are suspended in water. When applied, the water evaporates and the droplets
flow together to form clear films. These emulsions dry rapidly and require
multiple coats. The restorers require re-application about every 12
months."
I'm summarising now. The tester found little real difference between Poly
Glow and Vertiglas. Differences had more to do with clarity of included
directions and number and type of included applicators. The long term
results of this test haven't been published yet as not enough time has gone
by.
