How hard is it for "Great Sutff" to come off? Its a foam filler for houses and such. I took my wheel well liners out and the fuel lines are exposed. Im thinking about spraying it around my fuel lines to protect them. Im thinkin that a good size rock could rupture the line and do some serious damage. Spray that stuff around the lines and then hit it with some more truck bed liner and wolllla! Any idea if this stuff will come off easy or if it is pulled off, if it will take the fuel line with it? Thanks for the help!

I wouldn't do it. I got some of it on my hands right out of the bottle and it took over a week to wear off. I tried every solvent I could think of, water, acetone, paint thinner, mineral spirits, alcohol, and gasoline and nothing took it off.

I've noticed on areas where I've used it outdoors, it turns yellow after a couple of months in the sun and can be pulled off fairly easily, but there will always be a little left behind.

I was reading an article in Popular Mechanics about hydraulic cement for sealing around pipes in basements, and it said the cement is better than the foam stuff because the foam doesn't like to stick to wet surfaces. Now I don't know if the foam will stick to a nice dry fuel line thereby preventing it from getting wet and be fine, or what. Certainly can;t hurt to try it! I'm not familiar with the area, but maybe putting some sort of extra sheething on the line would be better? Almost like flexible conduit?

I saw this situation as well. I ended up putting my rear liners back in. I figure that if I am stuffing my tires that much in the rear, they are going to be tearing other things up first. Plus, I don't think my tires will fit up that far...

Just wrap the lines with a piece of heater or radiator hose and clamp/zip tie it.

I'm with CTKJ on this one. Those foam hose covers should work great for cushoining impact from debris.

Alright well I'm going to try that. This should also protect the hoses from road salt right?

The way I read ure post is that you DON't want the stuff to come off. Correct?
Well, I used it to seal around the overlap in my storm windows after I installed an AC unit in my bedroom. In the winter I put that clear film over the whole setup and a cover on the AC anyway (it's a real PIA to get the AC in & out in this particular window so I leave it in permanently). Of course, the AC died after a couple of seasons and I literally had to hack the stuff out with a chisel! It wouldn't break free no matter what!

I also used it to fill my rear hitch mounted tube step/bumper thingy because water was getting in and rusty water was flowing out. It was wet when I sprayed it in and it adhered like u wouldn't believe anyway.

Just remember, that stuff expands to many times it's volume so use it sparingly and trim it quickly before it gets too hard. (U should have seen it running out of my step for like 2 days after I sprayed it in. Looked like styrofoam icicles as I was going down the road! I used a full can!)

Water is no problem for Great Stuff. It is a closed cell polyurethane foam that is not supposed to take on water. Also a little water will not hurt it when it is curing, moisture actually helps it cure.
