    In any time, do some testing yourself. The environment you are working is is not a temperature controlled lab, and you are not casting TECAM 100 gram batches.

    Working with epoxy, keep in mind that moisture speeds up the resin. Also keep in mind that your glass may have taken an amount of moisture as well.

    About mixing curing agents: It can be done, just know what you are doing. Many suppliers now offer fast and slow hardeners, which can be mixed to your liking, without changing mixing ratio. But also when mixing ratios are off, it is just a matter of calculation.

    Humidity can trigger excessive blushing, coating in high humidity can be a real disaster. However, most suppliers should be able to offer an epoxy that is suitable for coating, without blushing.

    In very high humidity I would recommend resin infusion, as this way you can get rid of the moisture before you start mixing resin. Below 20 mbar you will cook off the water.

    You must not repeat the experts comments.

    You are a bloody amateur. And I am sure most of us are well aware of that!
