Yeah, it's messy. It's not regular paint for sure. I only used it in my wheel wells. I didn't want it to look like a truck bed but wanted some texture to sort of mimic the factory undrcosting. Most nyone can tell it's not original-appearing but it's close enough I suppose. Reducing it allowed me to spray it with my primer gun. (requires a larger tip though like a 1.7-2.0) It does not spray out like paint. I imagine the Schutz gun would have been easy to use but that seemed harder to control and likely more prone to making mistakes and getting Raptor Liner on stuff it wasn't intended to be on.
