Tail Light Housing Restoral Tip

Just finished restoring my tail lights and one thing I did may help people so I'll pass it on.  Not really mind blowing but useful :-).  When I took them out I noticed the "melted plastic" I'll call it that retained the nut and cap for each hole was so brittle it wouldn't hold the nuts in anymore.  Half or more of the 16 total nuts were falling out the back because the plastic the factory melted over was dried out and nearly gone.  It's a miracle the PO didn't lose these lights honestly.  Went to home depot got this fix it putty I've used in the yard to stop PVC leaks and it was excellent at repairing each nut placement.  It even dried an exact match to the color of the plastic housing.  What was nice was it was pliable and easy to mold before it hardened, unlike some of the epoxies that become a mess too quickly.  I didn't want anything liquid that would seep through to the nuts and ruin the threads so this was the perfect consistency.  I had to use a little of it on the inner side as well and it really did a great overall job strengthening the integrity of each hole.
