Okay, I see. How much alcohol should I mix in?
Old habits perhaps die hard, I use plain old rubbin alcohol (so cheap) and it has never failed me for, well a really long time.
Heat does work also but my preferance is to not have to pull out and put away the heat gun when I can just drip a little 'Rubbin' with an old acid brush.
To answer your question drip one drop at a time in to the just mixed epoxie bubble untill the mix turns milky white and the mixture will freely drip off your raised brush.
The working time for brushing is short so more rubbin drips may be added to extend a little. For this reason keep the batchs small.
