Hi all, done a bit of a search around and haven't found anything that suits.
I have been having a few issues with a couple of the metal screws that screw into plastic housings on my Tamiya buggy coming undone after a race.
What do people out there use for this issue? I see that almost all Loctite products react with plastic... Someone suggested superglue, but I'm a little hesitent to use this as well.
Any suggestions?

Why not just use basic CA glue that almost everyone has in there toolbox? Seems much easier than finding something new to accomplish the same thing.

CA Glue works well, just a few drops in the hole before you thread the screw.
Or, you can take a few strands off a car battery cable, stick them in the hole, and thread the screw. the wire strands will push into the plastic and help hold the screw.

These are all just temporary fixes. Usually this is caused by over-tightening the screws. Replace the plastic and just watch how much torque you use on the screws.
One method I use is when I use a driver I do not hold it with my whole hand.
I hold it with my thumb and 1-3 fingers. The less fingers you use the less torque you will use. Normally, I use my thumb and two fingers. Also, if you are using a power driver it can heat the plastic.

Use the tire glue that you already have.
Once a screw starts backing out of plastic it's time to replace that piece but in a pinch I use one drop of CA. It holds and will recreate threads in most plastics.
