Had a major paint reaction on a customer's 2018 F-150 last Thursday
I was doing a full respray on the bed of this truck, a metallic gray. I prepped everything right, or so I thought. I laid down the sealer, waited the flash time, and started with the basecoat. Within seconds, this crazy wrinkling and lifting started happening in a big patch near the tailgate. My heart just dropped, lol. I immediately stopped spraying and hit it with the air hose to try and dry it, but the damage was done. I had to sand the whole mess back down to bare metal in that section, which took me like two extra hours. I think the issue was some old wax or silicone in a scratch I didn't catch. Has anyone else had a reaction pop up that fast, and what's your go-to cleaner before sealing?
