Is it safe to use a hot-glue gun to keep LED's in place?

I'm building some LED headlights for my radio-controlled car, and I
plan to use one of those project boards or whatever they're are called
to wire my LEDs and their resistors. But my RC car is gas powered, and
the engine puts out a lot of vibration. I'm concerned that my big white
LED's will be tugging a little on their solder joints without some sort
of brace, and I would like to just use some hot-glue form a glue gun.

But I'm new to electronics, and I do not know if the glue would be too
hot? and I doubt it, but does the glue conduct electricity?

Thanks,

Thanks all! I guess I will go with the RTV silicone stuff. My only
other question is if the silicone will effect the light output... my
LED's project their light in about a 60degree angle, and I wonder if
the silicone stuff will refocus the light?

What would be the best way to apply the stuff... just at the base of
the LEDs, or totally cover the LEDs in a think layer of the RTV silicon
stuff?

Lastly, since this will be on my RC car, dirt and other stuff will soon
cover parts of my stuff. I use the general parts-cleaners that
mechanics etc. use... spray can. Will that eat away at the RTV silicone
stuff, or cause harm to the resistors and LED's? Would just using soapy
warm water be better...and just let it dry thoroughly overnight?

Thanks again,
