After talking to different trailer companies, I am more confused than ever.  If the trailer has an aluminum floor - which is supposed to be the best - why would you put a spray on liner over the top of it?  Sundowner says it is great.  Other companies say it's not necessary.  What are everyone's thoughts, opinions?

When I first bought my new USED trailer I took the mats out to clean under them.There wasn't much under them but, a small spot where shavings and urine had been trapped was eating away at the aluminum. I drug them out but had to call my husband and grown son to put them back in . I haven't taken them out since. Think spayed in or troweled in would be great. IMHO 

I got the Rhino liner sprayed on my truck bed when my truck was only about 2 weeks old.  The installers mentioned that it's critical to have it done before any rust starts.  If you spray it on after it's already started rusting it will continue to rust underneath. 

I've seen several new Sundowner trailers that had the rhino liner on the underside of the GN - gives it a nice appearance and will help it last a lot longer.  Good idea to have it sprayed inside the trailer as well.

I went to my local Line-x dealer and they told me they could not spray my aluminum floor in my trailer, now you guys are saying it can be done?? I definately want it done. We are having the Iowa horse fair next weekend and I am going to be finding out and looking at all the trailers to see if they have it sprayed.

Would rather have WERM but line-x would suffice.

Your Line-X guy is right. Talk to any S_______er dealer and they'll tell you they pull the sprayed in liner out in sheets off of 2-3 year old aluminum floors regularly. And S_____er doesn't cover it under a "hitch-to-bumper" warranty. The aluminum just isn't porous enough to get good adhesion in the real world on a consistent basis. And if uring gets trapped under a "loose" flap of liner, mmmmm....... it corrodes pretty quickly. So- sometimes it works, a lot of times it doesn't. WERM is much better for that kind of protection.

I found this website when doing a Google search for WERM.  For those of you who would like it in your existing trailer's, it might give you a lead. 

We had it put in our trailer when we bought it.  When the dealer offered it to us and we saw what it was, we jumped all over it.  Two women, with a combined weight of 250 lb. soaking wet with rock's in our pocket's, and I'm too darn old to want to pull heavy stinking mat's out of a 4 horse trailer!  Uh huh, ain't coming on that!  You can't get the mat's clean, so when they dry, they still stink!  It cost an extra 1K, best money I ever spent.
