Re: How to repair rust bubbles Reply #50 – 3 years ago Mark … I’d suggest you call the Factory for guidance. I’ve found them to be quite helpful.
Re: How to repair rust bubbles Reply #51 – 3 years ago Thank you.I called the factory regarding a rear window and frame install. They said they used Lock-tire and silicone.I may do a test strip before I commit to a larger section. .Mark
Re: How to repair rust bubbles Reply #52 – 3 years ago "Lock-tire and silicone."---Loctite (polyurethane sealant) OK, but silicone? For sealing what specifically did they say the silicone was used?
Re: How to repair rust bubbles Reply #53 – 3 years ago Silicone is used in sealing the window. Lock-tite used to secure window frame to window opening.
Re: How to repair rust bubbles Reply #54 – 3 years ago Additional photos.Photo 1: White caulk residue. Almost looks and feels like an acrylic tub and sink caulkPhoto 2: End cap gap and screw hole. I removed the screw. I will fill this hole then drill and install screws above and below this hole.Photo 3: End cap gap after removing old caulk.
Re: How to repair rust bubbles Reply #55 – 3 years ago Looking at a magnified view of Pic #1 I'd have to say it's not silicone and that whatever type of caulk it was, was applied too thinly to seal much of anything. It's not even adhering well to the fiberglass.
Re: How to repair rust bubbles Reply #56 – 3 years ago The Factory does not uses silicone to glue anything .They maybe using a polyurethane sold by Locktite.I know of no easy way to determine what type of sealant was used. Common solvents do not dissolve silicone or polyurethane. Paint does not stick well to either.Larry
Re: How to repair rust bubbles Reply #57 – 3 years ago For Larry.Due to crappy rainy weather I've not been able to calk my end caps.I purchase 5200 Fast Cure. You stated the tape needs to be removed immediately after applying the calk.No wait time??? Thanks!Mark

The 5200 Fast Cure skims over very quickly, wait too long and the tape tears at the edges of the sealant.Larry
Re: How to repair rust bubbles Reply #59 – 3 years ago So as soon as I have the caulk applied remove the tape?M
Re: How to repair rust bubbles Reply #60 – 3 years ago Quote from: NADAZE! - 3 years agoSo as soon as I have the caulk applied remove the tape?Push the sealant into the seam and smooth it out, using a gloved wet finger. When it looks good, pull the tape. Larry

Re: How to repair rust bubbles Reply #63 – 2 weeks ago Hi, I have been searching for days and finally found this topic to answer my questions. When I had bought my Lazy Daze, there was water rot on the back wall. They had to go in and redo it from both closets (I have a 30 IB) they didn’t go up higher which is where I have bubbles in my metal as seen above. I don’t feel out see damage inside there. I did have the entire rig scraped and resealed. I will go over it again to make sure nothing was missed. They had said that to go up higher they would have to take off the back wall and they weren’t able to do that. It was a resale RV Consignment Lot. I had called around and was quoted 20,000 for another place to do it. Since I had paid 26,000 plus another 15,000, I just didn’t have it to put out. Can I do this myself?
Re: How to repair rust bubbles Reply #64 – 2 weeks ago Hi Wendy; I'd have to see the damage from the aluminum oxide bubbles under the paint to really determine mitigation efforts. If the holes aren't too large, in the past, (not LD), I'd clean out the edges, Bondo and sand, touch up paint will make it less obvious. Primarily stop the water intrusion from above! Sounds like you have done what you can in that regard. Pictures help us assess how bad the situation is. Welcome to the Forum. RonB
Re: How to repair rust bubbles Reply #65 – 2 weeks ago I had the same issue with my LD. You must reseal the roof and end caps. Lap seal all vents, Eternabond the roof seams, recaulk end caps with White 5200 Marine Adhesive Polyurethane Sealant. Check the rear clearance lights. Factory clearance light are crap and have the tendency to leak. Once you have rust bubbles they must be repaired. Clean out the rust and oxidation. Fill with fiberglass Bondo. Sand, prime and paint.This is a big job. Take your time.Good luck

Can I do this myself?Removing the rear wall for repairs is a huge job for the pros, it's beyond the ability of most of us.Follow Mark's suggestion to make sure everything is fully sealed, including around the window frame and even resealing the gap between the rear glass and its frame. The rear clearance lights are probably the cause of the corrosion although I have seen protruding staples in the plywood sub-layment cause this problem when they touch the aluminum skin.Larry
Re: How to repair rust bubbles Reply #67 – 2 weeks ago Hi Wendi; A picture of the affected area would help us give you better advice. The severity has a lot to do with the difficulty involved. A high price from 'professionals", may just mean that they really don't want to do it. RonB
Re: How to repair rust bubbles Reply #68 – A week ago Quote from: RonB - 3 years agoHi Mark. I don't know what your expertise level is. Don't use any silicone sealer. Dap acrylic will seal for now, and be easy to remove. Eternabond is hard to work with, hard to remove, and meant for permanent repairs. Don't use that either. Same with 3M 4200, 5200 sealant. White duct tape applied carefully over the bubbles. It will make it worse if it traps more water in the wall, but if dry can protect it temporarily. The fact that you had a plastic back window was a bad sign to start with. Auto body repair people also aren't the best. They work with cars, and your motorhome isn't a car. No steel, and wood isn't what they are used to fixing. Lazy Dazes are peculiar, almost one of a kind anymore. OK Thor and others do use wood framing, but not the same way as LD. You need to find an RV repair facility, that can fix water, roof leak and other location leaks. You'll have time to investigate potential repair locations in the next month or so. RonBOh my gosh, I just saw this after I went out and put Eternabond tape over my rust bubbles. Do I go out and remove it really quick? I didn’t have any type of sealer and I paid the place I bought it from to scrape and reseal the entire rig but now I have bubbles in my back wall, same scenario, I’m guessing.

It could also be a long-term fix if you do not want to spend the money or fix it yourself. You need to determine if the leaks are still present, the end caps, clearance lights and windie frame are all suspsects.As Ron pointed out, do not use silicone sealant for anything on the coach, it poisons the surface and it will not accept any future sealant with sanding the surface to bare metal.Larry
