Ok I finally got my roof clean around the vent and free of ll the white sealer that had set up like concrete. A wire brush on the air wheel wouldn't touch it. I had to put the big grinder with a stiff cup to get it off and had to use pressure. What is this stuff? Do they still sell it? As hard as it was to get off it's still some good stuff. Kinda looks like the stuff on lady w's seams in her post vintagetrailertalk.freeforums.net/thread/1478/penelope |

This is a goop free zone LOL... We don't do goop here. But most of us have had to remove it and it sometimes makes you wonder. If it's so hard to get off, why did it not work? Shrinkage and expansion of the metal is why. |

The white goop could have been self leveling Dicor Lap Seal if it was around vent flanges and such. It's used all the time in the RV industry. There is about 15 different sealers used at the RV center I was working at. You'd be surprised at the different types and uses for each. Like; www.ebay.com/sch/i.html?_nkw=dicor+self+leveling+sealantFYI; normally sells for around $10 a tube and if you use, don't buy off feebay. The stuff at the RV center will be fresher. It usually lasts longer than the rubber roofs it's usually applied to! LOL After it FINALLY sets up it's bullet proof. Have NO CLUE what the heck that stuff is in the thread you referenced; vintagetrailertalk.freeforums.net/thread/1478/penelope |

Dicor never dries rock hard. It is always slightly malleable even after curing for years. I use it for my vintage vents, as it sticks to itself and can be removed, albeit with a lot of work.
My guess on the cement like white stuff is some sort of roof coating. It could even be white "silver slop", which is a horrible stiff roof coating and impossible to remove. It also doesn't seal very well.

This wasnt the silver slop we call Kool Seal around here, although it had it on it too. the silver slop came off easy and in chuncks to painted metal, this stuff i ended up using a 7 inch grinder and brush on. even then it was tough, and was definatly stuck to the metal.

I think I have the same stuff on the roof of my Vacationer. Not sure what I'm going to do but I think I want to replace the whole roof anyway. I haven't really got to it yet but the other day i was up there stripping the sides and just for kicks took my big screwdriver and could barely seem to put a scratch in it.
I think I will just try to take the roof off with that junk in place and just get some new metal.

I have black stuff, silver goop and some white stuff that sounds like the same thing. Tried to scrape it off with a screwdriver, nothing, so went to the heat gun. I worked really well! The
black stuff just got tarry, but the white stuff came off in chunks. Unfortunately I had already created scratches and dents before trying heat. And that was just the stuff that dripped off the roof onto the Eyebrow............................

Diesel fuel should cut anything that gasoline will and is much safer to use. Gasoline fumes will spread along the ground for a long way and one spark can ignite it. When I was a little boy my parents bought a house that was over run with trees and bushes. So they were cut up and piled as high as my dad could. Then he tried to burn them, didn't have much luck so he poured gasoline on the pile then realized he didn't have a match to light it with so he ran into the house got a match, stood back and struck it then threw it at the pile, BOOM flames traveled over a very large area starting several grass fires and caused the Menthane gas in the neighbors outhouse to explode blowing part of the siding off. This was right at the end of WWII so everyone in the neighborhood thought a bomb had been dropped. My dad quickly stomped out the unwanted grass fires then went out in the street like everybody else looking to see what exploded. I was sworn not to tell a soul. Oh the fond memories of childhood.  |

My dad told me about a twenty-hole outhouse they had on some Pacific island that they poured gas in to kill the odor... BOOM! We have liftoff! He said the whole thing took off like a spaceship then exploded in mid-air. I took the black crap off with a heat gun and my painter's tool (basically a very stiff putty knife with a chisel point, I lifted almost all the black crap off in strips), and the silver gunk came off with one of those paint stripping wheels that go in a drill. The kind that looks like a very coarse sponge. |
