Sealing the rubber roof with...

Hello All, several questions on sealing the roof.

Had a RV expert look at my roof and said it looked fine. I mention that i was going to put Eterna Bond tape over the front and rear caps and he said, don't use that tape on your roof period. He said that stuff is a mistake to use. He didn't go into details and I didn't ask him why. I read here that Eterna Bond tape is the way to good for sealing the e\seams on rubber roof. Question.

What's better lap sealant vs. Eterna Bond tape?
Can you apply the Eterna Bond tape over CLEAN sealant?

Please add other related comments,
Thank you

Can't imagine why he would nix Eternabond (or it's Dicor cousin, DiSeal Tape). It has many uses, as does lap sealant. I'm not one to put Eternabond everywhere, but I use it where appropriate and use lap sealant on the rest. It is very effective on relatively smooth surfaces.

I've seen a few people try to use it on ragged surfaces or fail to clean and smooth an area before applying it. It's not a miracle cure, nor is it the answer to every problem, but it's a darn good product.

GENECOP and Gary, yeah, didn't think his remarks were valid on the Eterna Tape.

Here's the attached pic of the rear and front caps. I'm going to apply the Eterna Tape as planned and make sure the tape's edges has at least 1" of smooth surface to bond too. I think this would be better than applying lap sealant, RIGHT?

Thanks

If you read the Eternabond instructions, the surface must be clean and smooth as possible.

I have always, removed as much Lap Sealant as possible, clean with mild soap, apply tape, and roll with a small flooring seam roller. You don't want any bubbles under it. Then seal the edges with Dicor Self-leveling Lap Sealant.

If you MH is not under warranty you can use what you want. If you have a warranty or an extended warranty make sure the material you use will be covered in case it cause problems.
I learned from experience.
