fixing plastic parts (this case the relay board cover), fixing cracked plastic Options

[eastbay851]

anybody who has a piece of broken plastic with which to deal on your car (or, i learned from continually getting off my motorcycles before they were stopped.) the best way to deal with plastic is to use baking soda and super thin super-glue. fill crack or chips with baking soda and apply glue. the preferred applicator here is a piece of tube filament. i get mine from a local hobby shop who makes their own super-glue but fly tie supply places have it. you can build up (in thin coats of baking soda) to 1/4" thick or more. i have made full loops with this method for the cowling of a motorcycle, dropped the bike again and the loop survived while the rest of the piece suffered severe trauma. one of the advantages to using this method... makes no difference what type of plastic it is. super glue does not discriminate.

Have you ever tried Micro Balloons?

I used to use this stuff back in the day fixing RC helicopter canopies and RC airplane fuselages. It is mainly used with epoxy, since it is coarser than baking soda, but is pretty handy stuff. Sands down to a very smooth finish.

I have, they are pretty cool. Used to fill my solid wings with them to sand out blemishes, but i used it with white glue usually, the epoxy or CA with them was to hard to sand around the balsa.
