Application Instructions

Application
As an overall or full-panel repair, allow appropriate dry times for primers and sealers. Confirm color match is appropriate by testing color prior to application. Strain paint prior to application. Apply one medium-wet coat and allow 15 – 20 minute flash or until surface is hand slick. Apply a 2nd full wet coat. If a 3rd coat is needed, allow 20 minute flash between 2nd and 3rd coat. For best results, do not apply more than 3 coats. If metallic are being applied, apply one fog coat immediately after last coat, holding the spray gun back an additional 2” - 3”. Raising the air pressure a few pounds will help even out metallics.
See Technical Data Sheet for more information on blending color, and one/two gun method to reduce blend edge.
