Size: 16 Ounce Aerosol Can (Pack of 12) Verified Purchase
IN SHORT: This is an awesome deal. I bought a case of these, only to find out that the case could coat my entire house. This is a lot of coating! I haven't even used one full can yet, and I've coated a whole bunch of random stuff, just testing out how durable the coat really is. So far, I have learned that it takes a few days to really cure properly to its hardest state. Also, if you use multiple coats, extend out the curing time further and know that the more coats you put, the less durable the coat becomes.

PROS:

Tough rubberized coating
Inexpensive per can
Enough for the rest of time

CONS:

Cure time can be lengthy

RECOMMEND: Yes (if you need plenty)

ordered a case of this product. it covers fine, lasts long, does what it needs to do. it does not go on as heavy is the tite-seal brand undercoating i had before, but it costs much less. good deal for the money.

Works great. I used the product much life the info commercials for "flex-seal". It will seal up about anything for a fraction of the cost.

I applied this stuff to 3 metal parts on my motorcycle, all the parts were pre primed and dried and cleaned before application. I left for vacation and returned 4 days later. when I inspected the parts the coating was still not dry, it flaked off in my hands ruining over 100 dollars worth of parts. still not dry after 4 days of 80 degree 50% humidity san diego weather. this stuff is of poor quality. do not apply it to anything.

Sprays nicely, coats evenly - but be prepared with paper towels and mineral sprits for clean up ( I did mine over a tarp which caught the majority of the drips) also wear old cloths (long sleeves and pants) - this stuff splatters when it hits the intended target (95% stays put so no complaints) 7 cans only did 50% of a f150 super crew with 6 1/2 ft bed. Ordered 7 more. Dries to a nice flat black - mine only took a day and a half (I drove it and the humidity was low so I'm sure that helped) very happy with the overall quality of the product - hope it helps keep the salt away from the body this winter.

I have been using this product for about 10 years and about 6 vehicles. It works great, no problems, the only thing to be aware of is it lasts for about three seasons here in Michigan and starts to fade away. I just power wash and re-apply. The second time I apply it takes half the amount of the first application. It's ALWAYS stuck and dries just fine. I've never got rust under my vehicles and it actually makes removal of nuts/bolts much easier because of that. Worth it, worth it, worth it..........
