If you have the old grill that came in the car, and it’s busted.....use it to fix the good one with cracks. Scrape some plastic shavings off of the old grill, into a dish. Get enough to fix the crack you’re starting with. Then add a little acetone into the dish with the shavings to make a paste. Have the crack V’d out beforehand, and seperate it just a tad with a toothpick or something. Add your paste made from the same type plastic, work it into the crack and then remove the toothpick. Smooth it out to a slight high spot, and then let it dry and work it out after is ready. It’s a good idea to drill the end of the crack to keep it from cracking further. Try it on a junk piece......it works!
