Thanks for the message John, yes keeping the jar constantly in hot water while I work is what I do, but still the product does not etch well, it's very soft and needs 20 minutes to give a result which is not the best.
I'm just comparing to how the product was in the past, this is completely different now and the fact that it turns into a solid at room temperature makes it unusable.
I'm wondering if anyone else is having this issue.
