No, this stuff won't let you build a Johns Bay 24 out of a screen door but it is great stuff in its own right. I've used it for several years and am continually amazed with its durability. I use it as a barrier coat/rust preventer and it is in that role that it excels (though it does a decent job as a penetrant too but I'd still favor WD and the like for that task). Not cheap but a real value, IMO. Highly recommended.
