RE: Bi planes
Don't know those terms. Best is denatured alcohol. We can get it here at home improvement stores and some pharmacies. It has less/no water in it than isopropyl alcohol does. You will need only a few drops. Use too much and it will not cure properly, it will stay gummy.
You can also use a heat gun to thin undiluted epoxy so it will spread easier.
Either way, use 30 min epoxy. the heat method will accelerate the cure time slightly.
