what did yall use

[CHUCKLEHEAD69]

does everyone use the black tar stuff under the frame or is there another way to go?

Asphaslt Emulsion, available at Home Depot in the roofing department. It's not very messy...

I used acrylic laquer. Or Boat bottom paint. I figured if it could seal a boat that sit's in the water all the time it should do a good job of protecting the bottom of my tear.

that what im thinking,something like that and pt ply should last for a long time

The only problem I can foresee with that is that boats don't usually have rocks kicked up at it normally. I'd be afraid of it chipping away.

I used NAPA spray on rubberized undercoating. Not messy as long as you keep your fingers out of it 'til it dries. Took two cans of it to cover a 4x8 surface with a thick coat. It's about $7 a can.

...4 coats of MinWax ClearShield thinned around 10% and sprayed on...it is a heavy bodied outdoor rated polyurethane and since it soaked into the ply, I am not worried about it chipping...or anything else for that matter........

madjack how well would fiberglass resin hold up, i thinking pertty good.just getting different ideas here also mj do u have insulation on top of that poly clear

[madjack]

Jude, not sure but I think the Glen used a thinned fibergalss resin(maybe)...the key is to use something thin enough to allow it to soak in....look at Doug Hodders tears...he use fiberglass resin on his outside and others do as well so it should work...

...the only insulation we have is in the roof....my figuring is that a 4/6" foam mattress is insulaton enough on the floor...after all look at a Camp-Inn, built way up in Wisconsin...that is the only place they use insulation...by the way they spray the bottom with a spar varnish........

There is a penetrating epoxy resin...although I haven't used it...I just did mine in oil based black paint...my original 49 Kit was done that way and I know it's still on the road, but then I live in a dry environment...I think that an epoxy would be overkill and expensive to coat the bottom...just my opinion...Doug

[SteveH]

Epoxy will thin nicely with regular alcohol and then can be applied like a paint. It will soak into the wood and act as a sealer...a very good sealer. Modelers do it all the time to the insides of model airplanes to seal them from any fuel leaks that might happen. Might be a little expensive to do the bottom of a tear that way, however.

down here i can get a gallon with hardner for 22 dollars(18for resin 4 for hardner)i seen some of the prices yall have it would be costly that way.but im looking at the same price as a good oil based paint.plus im doing the whole ttt. so i guess ill just do the bottom too.thanks for letting pick yalls brains

I covered the bottom of my build with epoxy resin, then house paint.

In the process of moving it around, before I attatched the axle, I punched a hole, which I will repair with epoxy and paint!! My build is frameless and the bottom panel is just 1/8" thick.

My plan is to regularly inspect the bottom, as well as the edges of the plywood I cannot easily see, and repair as necessary. I suspect an old hunk of mirror will come in handy for the inspection process.

I am not worried about wood getting wet if it can easily dry out, but trapped water is bad water.

Anybody try having the floor piece sprayed with Urathane (Rhino Liner) at places that do truck beds and other items... Have seem 4x4 frames and Rock Crawler frames and bodys sprayed with it, so it would probably work well for floor (underside) of TD.

Roly did because he had a hookup. He said that it is heavy though.
