Quantum99 Polyurethane Topcoat Base


The core of the Quantum high solids repairable topcoat system, Quantum 99 is a revelation. DIYers & pros alike can achieve professional results by brush, roller, or spray. Quantum 99 finishes have unmatched durability and gloss, plus superior stain and weather resistance. Unlike other topside systems, Quantum 99 finishes can be repaired by wet sanding and buffing.

  • Twice the solids means a gallon goes twice as far

  • Shorter cure times

  • Lasts 3 times longer than comparable paints
