bed liner spray for roof..., why not?

[mortimer]

ive thought about getting the roof of my 66 1500 sprayed with rhino liner. i had an est. of $450. thats a lil more than i can spend. the parts house in town has it in a spray can for less than $5. the rhino fella said they have never sprayed a rv but it surely wouldnt leak. anyone ever done this?

Interesting idea. Consider Line-X if there is a dealer there too.

My thought's would be

A) if you used a dark color like the standard black, it's going to be very hot.
B) if you ever need to repair the roof, like you clip a tree branch and bent the aluminum, it going to very hard to get off, and the last time I talked to a bed liner company they can't do patches. The whole thing would have to be striped and resprayed.
C) it will effect the resell of your trailer, as I for one and I am sure I not the only one, would pass on a trailer that had liner on the roof, or any roof coating for that matter!

But hey it's your trailer, do with as you want.

I'm with schweet on this one. Hopefully our moderator will chime in. It's not usually the "roof" that leaks but the seams. Best bet is to remove your j-rails on the sides, clean them up, replace using butyl tape under the rail. (gorilla glue toothpicks into the screw holes so the new screws get a good bite). Use dico self leveling lap sealant on the roof seams (between the aluminum panels) and then hit the rail edges with trempro 635. Then painting the top white with a good oil based enamel will protect everything and reflect the heat.

I agree with all above too.

Yup, me too! Coatings on the roof *cause* damage... when failed, water can creep under and rot the aluminum.

Bed liners are heavy. The white will cost more than black. I pass on trailers slathered with any kind of roof goop.

While I applaud people who are proactive instead of reactive...periodic inspection and tightening of all screws along the roof seams should be sufficient to prevent future leaks if the seams are properly sealed.

Your roof slopes slightly towards the rear for a reason, to shed water...any break in a roof liner will channel all water towards the rear under the liner...if there is no escape break in the seal along the back edge the water building up under the liner has nowhere to go, and even small amounts of "standing/pooling" water entombed under that liner will be up to no good.

I'm another Member who will not even consider a camper no matter how nice it is that has anything applied to the roof, other than the proper paint, unless I plan to strip it for parts and the rolling steel frame.
