So everyone says you can't paint the chrome without sandblasting it, but I'm a stubborn SOB so I went ahead and did it anyways.
I first tried plastidip. I didn't like the finish. I did like the black grille though.
I asked a vinyl guy about wrapping it and he said it'd need seams to get it right, and vinyl will get rock chips exposing the chrome.
Onto the paint. I scuffed it with a red 3M pad first. Next came 3 coats of SEM ecthing primer. Next was about 4 coats of SEM sandable primer. I sanded the primer with 220 wet, dry, then wet a few more times. Next came Spraymax 1K gloss black, 3 color coats. I sanded that down with 220 until it was evenly dull with no glossy spots. Next came 3 coats of Spraymax 1K satin black. I sanded that down with 320 until it was even, then went over it with a scuff pad prior to the clear. Last came 4 coats of Spraymax 2K. Sanded the clear with 1000 grit, 1500 grit, 2000 grit, 2500 grit, rubbing compound, polish to a shine. The 2K clear has a hardener you release into it and should be much more durable than any other spray can clears. We'll see, she's going to have 1200 miles put on her in the next 4 days.
In hindsight I should have just paid the $200 for the primed grille and had someone do it in a shop, but we'll see how it holds up. My paint buildup is pretty thick, but I'm hoping it'll help any chrome from showing if the clear takes a rock chip. I did it all outside hanging the grille from a fence with a tarp behind it for all the base work, and off my wife's shepard hook from her garden for the clear. I cleared the hook too with the extra
I've only done the polishing one step past the rubbing compound stage as of now. I'll wait a month or so to polish it all the way. Pictures to follow.
