Primer is an unfinished surface that will require a final sanding prior to painting. Primer is a great option for those looking to customize and/or paint the parts themselves or have a body shop handle the paint. Primer is not intended to be installed as is on a vehicle. There are no UV stabilizers in the primer coating and will, therefore, degrade over time when exposed to sunlight
