Thin like paint during application. But fills pinholes, seals. Two applications and it was done. Tons left over for another time, another job.

using this for around my bulkhead once per year. keeps the dripping out. Also works good on foundation and steps. No more painting. A can goes a long ways. A little pricey now but what the hell isn't with the tariffs now. Have to order the gray color on Amazon. Can't find it in any stores, only the black and white. Probably sells out fast when they stock it. A very nice light gray color.

First, I will list my scores for Adhesion, Ease of use, and Water Resistance. Then, I will elaborate and give my final conclusions. Adhesion: 2/5 Ease of use: 5/5 Water resistance: 2/5 Overall score: 3/5 Adhesion The initial coat stuck quite well with proper prep. I used denatured alcohol to clean the surface, then 60 grit sandpaper to rough the surface and help with bonding, and then another round of alcohol to clean dust. However, one coat will not give the desired results. Much like paint, areas lacking appropriate coverage are more visible when dry. This is where the adhesion becomes an issue. Proper prep, specially sanding, becomes difficult because this sealant is pliable even when dry. Its not possible to do more than the slightest scuff without the possibility of damaging the first coat. Due to the thick nature of the product, expect a lot of drips. The product is very runny fresh out of the can. Once the product is dry, the issues with adhesion aren't over. The commercials for flex seal (and the quality memes) make you believe the bond is like super glue on steroids. This is hardly the case. If there is any heat or any pressure this sealant will not hold. Heat causes it to soften, losing almost all integrity, and pressure will force water through the porous interior (caused by the aerosol delivery). Overall, the adhesion score is due to the drips on the second coat and beyond, and the lack of integrity at anything other then ideal (meaning low to no pressure and heat). Ease of use Apart from drips making an even coat difficult on anything not planar to the ground, this is as easy to use as you think. The most difficult part of the process is prepping. The nozzle is fairly accurate and in my experience didn't clog. If you intend to use this sealant in a tight space, the can may be difficult to manipulate. While the can states its a skin irritant, it's not terrible if you get some on you. The toughest part will be peeling it off. Smell is comparable to paint. Tolerable to use with an n95, though respirator will be your best bet. Smell dissipates in an hour or less with ventilation. I do recommend using nitrile gloves and safety glasses. Overall, very easy to use. Water Reistance As mentioned in adhesion, any pressure will cause fluids to seep through the sealant. Depending on pressure, could be a sweat, could be a drip. Due to the viscous yet flowing fluid upon first use, even coats are difficult to achieve, which in turn effects sealing. There are pictures on the can of "recommended uses". One shows patching potentially leaking roof shingles, however, on the rear text on the can specifically states not to be used in roofing scenarios. While advertising a flexible barrier (which was attractive to me because I wanted a sealant that would withstand thermal expansion), the actual mechanic of flexing significantly compromises the seal. Hence, most likely, the warning against using it on roofs, since the can heat up to 160°F during summer. Overall, the score is based on the fact in nominal pressure and temperatures environments this will seal and hold out moisture, but in anything else the seal is questionable at best. The overall score of 3/5, and as the title alludes to, means that this sealant is meant for low stress sealing, specifically in areas that MAY leak (and not WILL leak). While not the best sealant, its easy use makes up for potentia shortcomings in other areas.

I covered old spots on an old car that was worn. I used painters tape and thin leftover packaging paper to prevent the solution from running in places I did not want it to go. Sprayed it on, and peeled the tape away a minute later .Done! Very good coverage. Very solid. This is on Steel! Put some rubber gloves on and a mask for safety... and you are all set! I'm going to try the tape next!
