That is bad advise for something like a MH or Boat. we use a variety of cleaning products plus these vehicles travel down the road where they get rain spray off the road and wash from unknown sources. These have solvent and other chemicals that cause silicone for your house to loosen and allow water to enter. Also one they are applied you CAN NOT RE-APPLY it or any other type of sealants. I tried it on my boat years ago and found it to fail. would never use it on metal or my RV. Only used it on your house.

I've had great results with this particular product on my boat. Better in fact than the marine specific product I had tried previously. Have applied it in layers before as well.

I am happy for your experience. My experience is far different and have had that experience for 74 years. Once silicone in applied and fails you will never be able to put more silicone or other type adhesive in it's place. It is almost impossible to remove the old silicone even with grinding. I think it is perfect for houses. nothing work like good old 5200 permanently seal and bond marine issues. On MY MH I will only use what I have learned here on this and similar forms added to my own experience.

Grab one end of silicone sealant and pull, the entire run will come away quite easily. Silicone is losing favor with professionals in the building trades, but is generally popular because of its low initial cost.
It works even less well on your rolling earthquake/RV.

Quick question, I was pretty specific about the product I mentioned. Have either of you folks actually tried a tube of it?

of course - GE silicone has been around since 1965. I used it on my first home back in 1968 and now it is paintable. It still is not the do all product however.

read all the reasons GE states about the product. affected by various solvents and chemicals and surface adhesion is generally poor.

Frequently Asked Questions About Products, Applications, Troubleshooting, and More
here are a few reason never to use the product on the MH or Boat.

Can I apply new silicone on old silicone?
For the best adhesion, we recommend removing the old silicone. New silicone will bond to old silicone, but the bond is not as strong as if it is adhered to a clean surface. If you choose to apply over old silicone, the warranty is void.

Some materials, such as concrete, soft woods, stone, specially treated metals, plastics, or other man-made materials, might have unpredictable surface characteristics. Therefore, we recommend that you test for adhesion by applying the caulk

Do not use silicone caulk on any galvanized surface. Do not use below the water level. Cleaning with detergent or soap and water is not recommended because silicone will not adhere to surfaces with any soap scum present.

Yes; caulk differs in formulation and intended use. Its physical properties, including adhesion, flexibility, color, opacity, finish, elasticity, and durability vary significantly so it's important to select the right product for each job.

Specialty: For a project that is beyond a typical home caulking application, or will be used in conjunction with another caulking product, or when caulk isn't appropriate for the job, a specialty product might be needed.

Those reason and many more is the reason I do not use Silicone products for sealing.
Since I have used well over 15 different types of sealants - some good some poor - I am well aware of Silicon products and only use them like they recommend - "Kitchen and Bath" sealants.

Anyone who has used "GE 100% Silicone II clear", or any other "silicone" caulking on the exterior of their RV knows that it does not hold up well... and that it will not stick it itself.
"Dicor Self-Leveling Lap Sealant" and "Geocel Proflex RV" are two that do.

I'll give that Geocel product a shot and see how well it performs. (I suppose I would be a hypocrite if I simply generalized similar products without actually using the exact item now wouldn't I?) I have used Dicor before on roof applications and I am very satisfied with it.

I will also keep a watchful eye on the areas that I applied the GE 100% Silicone II and post my results if I see any signs of failure.

One trick I use for water leaks is to stuff newspaper around suspected leak points. If newspaper gets wet, it shrinks, and you can easily tell that it has gotten wet.

I also lay a sheet of newspaper under kitchen and bathroom sinks after I do plumbing work, then check it the next day. this will show up any "Slow" leaks.

Regards,
Dan
