I hear ya! but what you want is mechanical grip. Rubber is not 'mechanical' like a sleeve or epoxy. Rubber has poor 'memory' and will let go. If the flanges are only 1/4" deep, then use a blind rivet or blind threaded insert (absolutely no chance of coming loose). But maybe that is to much hassle (not much room in there granted). Then may I suggest simple hard wood dowel. Rough up the plastic, then insert a dowel soaked in glue (note: at this time I don't which glue). A hard wood dowel will swell as the glue impregnates its fibers, making a very tight plug. Note: You want a glue that is fairly 'runny', and has a slow set-up time. But you will also want a glue that is not affected by gas when DRY, and has a good temp range! There are several that meet most of these criteria, fewer have the necessary temp range.

Paint >> I have found any 'metalic' paint is runny, and splotchy. I also don't know why. But they still look good!
