Review: Boat repair! Win. - Thickens epoxy very well so I can do horizontal and whole filling applications. Used this instead of getting the west system. Great.
Review: I was not expecting glass powder.... - This milled fiber glass is ground to the same consistency as powdered sugar. Package and listing could have specified that. It would have been better if it was labeled as ground glass (there is no fiber). I was kind of expecting some visible fiber.
