Well I have helped one of my buddies use the DIY roll on stuff, it works fine, just seems to be a little bit thin, an I don't know how long it will hold up... since the DIY stuff still isn't that cheap, an its for a dump trailer I would call like Rhino spray on because, there's is a lot more thick when applied plus would prob hold up better an its got a lifetime policy.

So you can chance it with the cheap stuff, may work fine for what ya need, but I would pay a lil more an get the real deal an not have to worry bout it.
