Good info.

I've always used Krylon Semi-Flat Black but it was discontinued from their consumer lineup I think because of its lacquer base. It dries so fast you can touch or re-coat within minutes. It's my go-to for JBL baffles, motorcycles, and cars. I recently found the replacement industrial version and ordered two cases.

It now goes under an industrial number: KRYLON® 1613 Industrial ACRYLI-QUIK™ Semi-Flat Black Acrylic Lacquer Paint - 340 Gram (12 oz) Aerosol Can SGP118690
