this review title is: great for not so common uses and the content is: when faced with the daunting task of replacing a drain tube in a boat one asks themselves how the heck am i going to coat the inside of this opening with sealant 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 was not 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 will be darned if it did not get the job donethere is a use for everything and it turns out that these hair rollers are good for more than just one thing i cannot 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 hairgreat product highly recommended no matter what you need them for.there are other information for this review, one is this reviewer did purchase it and the other is 6 people think this review is helpful.
