68 Charger front grill plastic repair

[Frankb]

Kind of has the appearance of an asphalt roof shingle. A google search will show pics. Most automotive plastics back in the day were some sort of abs. I went to a local plastic supply house, drove around back and looked in their dumpster. Lots of scrap pieces . Amazon has sheets about 10 dollars. I don't know about JB plastic weld. I used ABS cement from Ace hardware and it worked perfect. It melts the plastic and when its dry its like a weld.

I saved this years ago.
Start with 100% pure Acetone, buy a gallon.
Pour an ounce or so intp a glass jar (small open mouth jar). Take a scrap grill and using something sharp, scrape off peelings (like pencil shavings size) into the jar of acetone. Put allot of shavings in, the acetone will gradually melt the plastic into a goo. Add enough plastic until the goo reaches toothpaste consistancy. Once you have a good batch melted put the lid on the jar tightly and set it aside. Now, prep your grill as normal, V out cracks on both sides, etc. Use clamps near the joint to alightn the two sides flush and parralell. Smear on some plastic goo, leave it crowned up over the crack like a regular weld looks, let it cure overnight. Sand to flush the next day, fill any pinholes with JB Weld. The crack will practically dissapear at this point, paint as normal

Here's the one I used plastic weld (epoxy) on, it was pretty bad.

Cool! I just ordered a 1/4" sheet of ABS to repair/reinforce broken tabs. The grill is in pretty good shape except for those things so don't need goo for now.
