Sealant turning to dust on top front cap
So, I cleaned off the bugs from the front of the RV a couple weeks back (light dawn soap and warm water only), and that included wiping down the sealant on the top of the front cap attaching it to the roof. Today I went to clean off some debris and noticed white chalky powder coming from the seal area. I touched the sealant and it dusted my fingers like I just ran it down a chalk board.
Did I just screw up majorly, or why is it doing this and what can/should I do about it?2021 Reflection 31MB 5er

While a chalky, powdery residue is common with the lap sealant and roofing materials, dishwashing detergents are not recommended for use on RVs. They are designed to cut grease and can strip away protective coatings such as wax, etc. That said, with one-time use, I doubt you "screwed up majorly." In the future, use mild car wash products on the roof. Wash Wax All is great for the rest of the RV. There should be a section in your GD manual on roof care (you can download a PDF copy from the GD web site - very handy!).

You should have an Alpha Systems roof. Check out these links.

If your sealant is chalking you probably want to look into it more. My sealant collects a lot of dirt but cleans up pretty good with soap and water but does not chalk. Wash it good then watch it to see if it chalks.Last edited by Always Learning; 12-24-2021 at 10:40 AM.
