I've used the "bad" stuff before and that Quark is still working perfectly fine. You just have to be VERY careful to use a really thin layer so none of it gets squished out the sides and falls on the contacts. Getting some on the drain or source leads probably isn't as big a deal as getting it on the gate lead. WIth the other stuff, you can be a little more liberal, but still keep it thin for best results. Oh, and clamp it good while it's drying for best results.
