Painted this car with a single-stage metallic (Tikkurila Temadur 90) yesterday for a friend of mine. This was my biggest undertaking so far. I've learned that single-stage metallics are extremely tricky. I practiced on one fender, four doors, and two hoods (some of them more than once) to get the gun settings right for my WS-400 1.3HD. Despite all that, the first panel I sprayed at my friend's garage immediately started showing tiger striping. If you spray too wet, the flakes start swimming and you end up with tiger stripes or blotchiness. I was constantly struggling to find the happy medium between acceptable orange peel and good flake control. This paint definitely needed a control coat, and that's what fixed the sunroof, too. There were some dust issues in his space, but he's very happy with the result. No runs, no tiger stripes, and the orange peel is relatively uniform. His own attempt at painting the car hadn't gone well, and taking it to a professional shop wasn't within his budget. He also wasn't willing to switch to a basecoat/clearcoat system. Personally, I don't think I ever want to touch single-stage metallic paint again. I lived under constant stress for a couple of months planning this spray, and I'm so happy it's done! 😆
