Whats good to use on plastic bodywork? I heard acetone can meld pieces back together.

Greetings:
Acetone exposure does soften the plastic after a while, and you might even get the broken pieces to stick together, some. However the bond won't come close to strong enough for the tab to hold the panel on. Somewhere in the Technical sections there's a "Quick 'n Dirty" plastic repair featuring "All-Purpose" cement for plumbing from Home Depot and a backing made from fiberglass and/or carbon fiber matting. That really does make for a durable repair, but you have to bridge the gap between the panel and its broken tab to give it any strength.
Edit: I misspoke, it's
"Cheap and Dirty".

Super glue and baking soda will rebuild tabs pretty easy! Best to go to a hobby shop and buy super glue in the large bottles get thin and gap filler and a bottle of accelerator spray. Oh wise wheelman and his way is likley the best solution but if you can't get it to work the super glue and baking soda will be the way to go. You can get creative with paper or business card stock to hold the glue to pour a little soda on and build up the shape you need. I have rebuilt many parts that way. I have even rebuilt a plastic gear in the gear box of one of those little 6volt ride on toys, glue and baking soda then sculpt with the die grinder or dremel with the small diamond cutting wheel.

Super glue is the most important tool in my tool box! I'll have to do a tutorial when I get some time. In the meantime I'll look for a good YouTube video. I have rebuilt a couple broken tabs on my aero 80 with super glue

2 part 5 minute epoxy works great also, fixed some broken tabs on the plastic nose of my corvette with it

Mek methyl ethyl ketone I think it stands for and it works well but you need the broken pieces to glue back together. You can build up what's not there with the plumbers glue.
