silicone glue for potting my high power led system?
I need a little guidance.
I've searched the internet and I can't figure out what silicone to buy? I'm looking for something as cheap as possible, but it needs to dry clear and feel somewhat like rubber when it is dry. Can someone help me find a CHEAP product online that will allow for this?
Or maybe I should use epoxy? (would that come out really hard and plastic-like when it dries?)
Also can someone point out the pros and cons of using this method? Will the epoxy increase the chances of the circuit overheating? Should I embed heat syncs against the mosfets and leds or what?
An example of this occurring is in this instructable:
