    Cheap epoxy potting compund with green Mixol?

    I don't know if this has been posted before. But here it is. I was recaping an old 9600xt card and the iron sliped and took out a trace. I got it fixed just fine with a trace pulled from a junk board. Can I subsitute the potting compound with West System epoxy (composites) mixed with a slight tint of green Mixol, then styrene thinned and airbrushed on (2mil)? Whats in that expensive potting compound that makes it so special and expensive (probably no diffrent than any other polymer epoxy)?

    Thanks

    Thinking about it. I'm going to have to lay 1/4 inch pull tapes around the ram chip. Then brush on some silicone conformal coating, and immediately pull the tapes. This way the ram chip is encapsulated with a peelable mask. Then I will have to mask around the repair area so the whole board is covered will pull tape as well. This way I should get a complete even coat without wetting everything.
