You should consider XPEL on the spoiler too. Given that anything that comes out of the trunk goes over the spoiler, it's prime area for scratching (esp if you have kids that are trying to "help")I've got Xpel, full front and rocker panel and side vents. The rest is paint. I'm looking for a good sealant to go over BOTH those materials. Not the "permanent" sealants, but the routine "wash and wax" sealants.
