Thanks for sharing, but I have some questions, first the video says 40 liters, and in the end if you add it up it's 32, second, petroleum is a general word, what is the name of the solvent and the name of the lead blotter and finally you say 20 kilos of resin, but 20 kilos is a drum or bucket full of the container from which you take it and you don't see the amount you say, it looks like you added less. Thanks again for what you share.
