I have used this, and there are a couple comments for beginners. None of which have to do with the quality of the product. 1. This is wipe on wipe off. Do a section and wipe it off immediately. Yes, immediately. It will still be wet. CHANGE TOWELS OFTEN. If you dont wipe it off quickly, you will end up hiring the weightlifting teenager down the street to wipe it off. It gets hard quick. 2. Remember, you are wiping a liquid off. When you set your rag down, the coating will transfer to where you set the rag down. Always check that after picking the rag up. If not, you will leave high spots, and you will be angry. 3. If you go past the section you are wiping off, your rag will carry that liquid with it. You must check where you over wipe or you will leave high spots, and you will be angry. 4. Wear some type of gloves, as the coating will transfer from your rag to your hands. If you touch your paint with bare hands, AND gloves, you will leave coating behind. Always check where your hands have been and wipe it off. 5. If you dont finish the job all in one go, wipe the mouth and threads of the coating bottle clean before putting the cap on. If you dont, you will have dried coating falling on the block you are putting the coating on with. 6. Do not do this in deep shade. 7. I suggest when setting the rag down to apply the coating, set it on glass. The coating left behind is easier to see.
