If by chance it's a pigmented or pearl additive in the clear, then this will be the final nail in the coffin for Cactus Gray as something i'd want on my car. Pearl's are a huge PITA with any re-spray, or having anything color matched at a later date.I’ve heard it called shiney primer before. Which still has me up in the air I may just go oxford and call it a day!! Honestly I have no idea it’s a hard call!
If it's in the paint layer then it will be drastically easier to work with.
