Sealant for roof seams and joints

[ctrain22]

What does everyone recommend for caulking and resealing the seams on the roof of your rigs? Brand, type, etc. The roof itself looks good but he trim caulking looks a little sketchy.

Someone told me not to use Flex Seal, that it will eat away on the roofing material. Anyone experience that?

Thanks

We really need you to fill in the blanks for us… Year, Model and floorplan of your RV.

Winnebago has very specific sealant guides detailed by year and model for most of their RVs, and you are correct FlexSeal is NOT on the list.

Help us help you and always include your RV’s details in every post.

Mine uses the clear Pro Flex stuff

My model is a 2000 Minnie Winnie 30ft WF430V class C.

Do you recommend I try to remove the Flex Seal I already applied to some areas?

Any recommendations for the best sealant? What about the tape type I have been seeing?

Thanks

It would be good to learn how to find info about your motorhome online from Winnebago.

For instance... here is a link to the sealant guide for your motorhome. It will tell you want to use on your RV.

You will find links to all kinds of documentation, parts, lists, diagrams etc for your 2000 Minnie Winnie. If you go to:
https://winnebago.com/owners/owner-resources

On that Sealant guide you'll see Winnebago part numbers. You can either order those part numbers from Lichtsinn RV OR... what I do is do a google search for that part number and that usually gives the the name brand.

For instance: Sealant A 072289 is Manus Bond AM75
Sealant B and C are: NuFlex 311 or Hengs 311 Silicone

The small numbers in the parts list are for color like, black, white, clear. That doesn't matter as much as the brand and that it is either silicone or urethane depending on location.

As to the FlexSeal you've put on there???? Who knows.

Does Winnebago update the sealant info to reflect advances in product quality, or am I seeing what they used way back when it was new?

I’m not 100% positive but it does seem that their part numbers for various products changes in the sealant guides. Where Manus Bond 75 A-M used to be prominent they now spec Henry’s Roof and Gutter.

My perception is that they don't update previous callout sheets once they've been published. It's always good to look for current recommendations. Lichtsinn RV is also a good site for sealant information.
