    Ok folks in a few weeks I will start my roof repair. Any and all advice etc is needed. I want to use the kiss method of possible. So I will post a few preliminary pictures, yes it needs to be cleaned and thoroughly assessed, but my preliminary findings are:
    Lots of crazing in the roof.
    It's solid, nothing is loose or heaving.
    There is one large crack, but it's not loose from the fiberglass beneath it.

    What is the best way to fix this so I can use it soon. I would rather not pull off all the abs if possible. Even a temporary fix that will last a year will do for now, it's more about the time then money . I've fixed a lot on it allready . Thanks. 20180617_172415.jpg 20180617_172405.jpg

    Whatever you do..... don't use flex seal!!! From the photos it does look to bad. As for fixing it I would have to see it up close.

    Ok so closed up the pup. Now some pictures , and I did scrub it for an hour with bleach and dawn. I will need a bigger , stiffer brush. The car brush just ain't cutting it! Most of the cracks are crazing , and the only big one has movement. Say 1/8 or an inch or less. Over all it's sturdy and solid. I'm thinking of doing the and slurry, fill the larger crack and then grizzly grip the top. A.c. dosent leak , so I'll leave if for now, I can always fix it in the future. Gasket is worn , but o might be able to get another year out of it. I spent too much allready!

    I would skip the goo and use an ABS rated epoxy. Not only is it easier to mix up, it will be a stronger repair. Since you are planning on GGing the roof, you won't see the color difference.

    Might be worth a shot......now I have to think, lol. Grizzly Grip is ordered, I also sprung for new seals( I didn't want to but, in for a dollar in for a pound) so I will continue to clean the roof tomorrow, I'll get on top and scrub , hopefully I will not slip on the bleach and break a leg!

    Ok so cleaned up the roof real good last week, got some materials today and will start the repair soon. As it's mostly superficial cracking , I'm unsure of how best to patch. On the biggger crack i drilled some hole along the crack and lossened it to absorbe the water inside. I did test some of the other cracks but they were dry. So only one big crack. I will expoxy it down to the fiberglass undersiding, and put a strip of fiberglass tape over the crack. I will then use the abs goo to go over the repair. It seams to me the biggest problum with these roofs is that when they get a crack that causes a small amount of water in between the abs, and the fiberglass. Once the water gets in the sun does the rest, it expands the water turning it to steam further widening the crack, additionally in cold weather it freezes, so the constant expanding and contraction of the roof caused by water seems to be the weak link. If you seal your roof regullarly, I think it will outlast the traillor. I've seen this happen on roll down roofing.

    My Slurry wasn't exactly slurred yet, but I made the best of it for a first coat. I used some fireberglass tape as an extra support. My Slurry didn't absorb all the pellets yet so it was more of a thick paint, glue. I used it for the first coat, I'll put a heavier coat on soon. I have to work tomorrow and wasn't sure if water would get into the work I allready did. I also used it to fill in the micro cracks in the front. 20180625_111912.jpg 20180625_112113.jpg 20180625_181952.jpg 20180625_182044.jpg 20180625_111912.jpg 20180625_112113.jpg 20180625_181952.jpg 20180625_182044.jpg 20180625_111912.jpg 20180625_112113.jpg 20180625_181952.jpg 20180625_182044.jpg 20180625_182044.jpg 20180625_181952.jpg

    You might find that the consistency you used is easier to work with than a thicker one. You want flow without sagging.

    I'm thinking your right, after it dried I'm happy with the results. I will apply a second and maybe 3rd coat this way. I can atually feather it out to not seam as it was a repair, almost like spackle on a wall.

    Just wanted to say thanks for showing your steps here! I do not have the large cracking, but will be tackling my roof later this summer or next.

    Ok , so I got off of work a few hours ago and put another coat on, I can't seam to get the slurry thick, but that's ok. I wiped the roof down with the mek, and painted on a skim coat of the slurry I had , it was almost as think as school glue, but just not therr. I decided to fill in and skim over the micro cracks, the thinner slurry slowed me to do that. I will sand and paint as soon as the grizzly grip comes in. I used a foam paint brush. I poured on the slurry, let it seap in the cracks then Smooth it over the top of them. Was this necessary? Idk. But I had it ready and it didn't take long. Sanding will be harder, but that's what palm Sanders are for!

    Ok so today I sanded the roof with 80 grit paper and a palm sander. I removed the seals. Then I wiped down the roof with Mek and got a coat of the grizzly grip on it.
    Grizzly Grip is sticky and cures fast. So I thought using my banana roller would stop some of the runs that others ran into. Nope. Just the nature of the beast. I used a small nap, and didn't put it on heavy. But as the paint dried it required more and more to be able to lay it on. It is also imperative that you work quickly as the laps will pull up if you wait to long. I did pre stir the paint, but by the time i got to use the next bottle it needed to be stired again! I left the a.c. on and painted around it, I figured one less thing to mess with this year. If needed I will remove and touch up next year. I made sure to listen to all the warnings about the mek, I ignored all of them. Lol. This stuff I think is the same a a wood stripper I used to use (cleanwood?), my hands are a little dried out. But I haven't grown two heads yet. I also didn't tape or cover anything. The smaller roller gave me better control , so only one drip where it wasn't supost to be. I cleaned up the paint roller and my hands with the mek. Worked great.
    So we will see how it dries

    Ok second coat is on. I will take pictures later. It looks ok, as long as it's sealed right! I did notice something, where I repaired one of the cracks , it heaved a bit. This goes back to what I had thought. There was still moisture inside the roof, it traveled to a new spot and heaved up the abs from the fiberglass. So, for now I'm not greatly worried, but it will have to be cut open in the future to let out the water and resealed. Other then that I'm happy.
