There is mention of heating the resin to acheive a more brushable product but you will still decrease the pot life of these two part compounds. I have with several Mfgs material but mostly Devcon mixed to recomended porportions small amts and then thined by adding two or three drops of isopropol alchol. The material still sets up cures in very close to the specified time . No difference in long term quality has been noticed.
Good Luck saltRon <*}}}}><
