Product conform to its description, easy to use. I did not need half the tube just for my furnace glass. I let it dry 48 hours to be quiet and then I easily removed the cuter seal sticking in places. As explained in the manual must not be too pressing the glass on the joint to leave a small thickness between it and the glass. I heated oven at 250 ° for 1 hour to test and is nickel. For the nit-pickers might say that the manual is in English, but hey, it's not rocket science. Product to recommend.
