Speed of Installation
Polyaspartic cures in hours. Epoxy takes 24–72 hours between coats. For a 1-day install, polyaspartic wins outright.
UV Stability
Alabama sun is aggressive. Standard epoxy yellows within a year in a sunny garage bay. Polyaspartic stays color-stable long-term.
Hot-Tire Pickup Resistance
Both properly-installed systems handle hot tires — but marginal or thin epoxy fails first. Polyaspartic's tighter cross-link density gives it a safety margin.
Cost
Epoxy is cheaper per gallon. Full polyaspartic is 20–30% more installed. Most Huntsville homeowners choose an epoxy body with polyaspartic topcoat — captures 80% of the polyaspartic benefit at closer to epoxy pricing.
