I have had some good luck with JB Weld on some difficult attachments, using some kind of re-enforcement like DLW suggested. The best super glue Ive found is Loctite QuickTite with a spray of Insta-Set accelerator. May not need the JB weld if it is re-enforced. Heres a pic of what we have used the broken F-1 nose wings for (well I gotta confess that I broke em off intentionally before too). The 3 orange cars use them for the spoilers.
Good luck with your repairs-Circle Track DAC
Hahaha I like option 3 sorry been sick of late so was not up to replying.. I actually found these two cars in question they have been in a box for 9 years so the wings are long gone.. hmmm I wonder if a walrus nose on the Honda would scare the Williams fans?
We start with broken TYCO Indy Bodies, cut them down to basically save the body mounts and flatten the top to glue sheet plastic to them, then cut sheet plastic sides and glue them on. The roof is also made with sheet plastic, shaped, cut and glued on.
If you look close you will see we even reuse the windshield off of the Indy bodies, cut down for the air cleaner guard on the hood.
We've build a few of them using the ferrai bodies (TYCO), if you look at the prev. post pictures, the #1 "Baby Ruth" White latemodel is constructed this way.
That's what happens when old guys play with little toy cars and consume certain beverages at the same time!
