Enhance the coupling abilities of your favorite polysulfide compounds with PPG Aerospace® PR-148 Sealant Adhesion Promoter from SkyGeek. The promoter is blue in color so it's easy to see where it has been applied. The one-part formula comes in a pint-size glass bottle, so you'll have plenty of promoter to use on virtually any project. Designed to be applied with a brush or a clean piece of gauze, the promoter goes on smoothly and cures at room temperature without the need for any specialized equipment. The additive is priced competitively, but volume discounts are also available for an even better buy.
