Here are a few tips to get you the best results you can out of a product like this (there are many and they are all basically the same)
1. Choose the right kind of Flex Seal. This may seem obvious but there are several kinds of flex seal and they are all used for different things.
I. First, the rubber patch/tape is used for large cracks and or holes where you have full access to the area around it. The tape is very thick and can sometimes be unruly. Lay it flat out, cut it, and then roll it while keeping tension on or slap it on like in the commercial. Do not think you are going to move it around and reposition it. You won't. It's a one shot deal for best results. The tape, size to be at least 3-4 times bigger than the hole you are trying to close up. The tape can handle the most pressure in the product line. You must have enough surface area for the tape to get a good grip around the hole if you plan for it to take any kind of real pressure.
II. The roll-on stuff is great for large coverage where you want to get fancy putting on thicker and thinner coats here and there. It applies like a sticky paint. I would say that the paint is the most "accurate" because you will use a roller or a brush to put it on and you can make sharp lines, stuff more material in gaps really easily, and handle uneven surfaces nicely.
III. The spray is for quick easy jobs as is the weakest under pressure. It's great for sealing things like sky lights, thin plastic objects, joints on gutters etc. Anything that won't see a lot pressure behind it. It's harder to put on thick, but if you apply it like spray paint you can do amazing things with it. Thin, even coats, in a sweeping motion, over and over again and you can cover just about anything.
IV. The flex seal one shot caulking is really just like almost any rubber/silicon caulk. I've only used it once and was not all that impressed so I tend to stay away from this one and use 3M stuff instead.
2. Pick the right color for your application. The Clear does NOT stay clear. It has a tendency to turn yellow in the sun. If you don't mind that, or won't expose to sun or much light, then the clear is fine, however, I usually stick to white or black. PRO TIP: You CAN mix the colors of the roll-on to make different levels of gray. I am sure Flex Seal would frown but it works for me. It takes a lot of churning to get it all mixed and not streaky. Your mileage may vary.
3. Use for the right jobs. Don't expect this to seal high pressure water or stop a leak in a tire. There are limits to its flexibility too. When you can, seal from the inside AND the outside. Use the tape whenever possible as it works the "best" of the products and is insanely tough.
4. A little goes a short way. It doesn't cover as much area as you would think. Always get extra.
5. Using a screen door in the commercials wasn't an accident. When covering a large area, stick a screen type material to the area and screw it in place. Then use flex seal to cover the gaps in the screen. Use many coats, go slow and the kind of gimmick you see in the commercial is possible. If you cut a 4 inch by 4 inch hole in something, don't expect flex seal alone to seal it. Use a backing material.
6. If you are getting bubbles in the flex seal spray you are putting it on too thick. Relax. Put on thinner coats and apply slower. Give it a few minutes to get tacky, then retry.
7. Final PRO TIP: CLEAN THE APPLICATION SURFACE. This one is a no brainer, but over and over again I read about people not doing the prep work. Using de-natured alcohol is best if you can. It leaves no residue and on a clean surface like that it makes Flex Seal stick like you wouldn't believe. This is the most important thing other than choosing the right kind of flex seal to use IMHO.
P.S. One more thing you can do is use painters tape or the like to cover from over-spray. Really if you treat it like a super thick paint, most of the same principles apply.
