A little skeptical I was when I look at the Moltofill-Tube ordered. However, in the first application I was thrilled. After kneading the Tube you can immediately smaller and spray Medium holes with the tube. Then with a spatula (I prefer the Japan spatulas) smooth and after an hour everything is cured and almost out of sight. Now just grind and paint over.
The Tube is (also not craftsmen) highly recommended !!
