Review title is Great for not so common uses! [SEP] When faced with the daunting task of replacing a 15" drain tube in a boat, one asks themselves, "How the heck am I going to coat the inside of this opening with sealant?"<br /><br />Did a little poking around Amazon and I found these wonderful hair rollers that were just the right size to get the job done. It wasn't pretty, as I coated the hair roller in tan-colored sealant and then repeatedly inserted the roller into the boat to generously coat the insides of the hole with sealant, but hey, I'll be darned if it didn't get the job done!<br /><br />There's a use for everything, and it turns out that these hair rollers are good for more than just one thing. I can't say much for how they do with hair, but I can say, if they can handle the abuse that I put them through to get the inside of a hole in a boat coated with sealant, they should hold up just fine for hair!<br /><br />Great product, highly recommended, no matter what you need them for!
