Coating issue, What is going on?

Keystone 31MB 2021. Not a painted surface. Round area with thin edges appear to have flaking, can't see flaking unless you get very close. The area missing the coating seems to be slightly darker like a cream color and still has a shin, but the RV is a white ish color. Trying to figure out how to upload a picture. No damage just trying to figure out what the coating is so I can repair.

  • quite often there would be a paint/gelcoat surface sealant applied at the dealer and have to be upkept every couple years to keep the paint warranty.  it could be that coating starting to wear out.  it is not a ceramic coating but it is something like that.  it is a keystone sprinter so defiantly won't have paint, but rather gelcoat.

      Thanks for the info. I wish I could show y'all a picture of it. I can't even find anything like it online, other than chalky gel coat or clear coat on cars, neither of those are what I'm seeing. It's a light film that "looks like" a thin layer of clear coat flaking. I now know it's not but it flakes like it. There does not seem to have any damage to the wall itself. Where the coating has come off it is a darker color than the area not effected. I found some gel coat at Montana Paints but it only comes in white. I'm more concerned about stopping it from growing then looks but being where it is I would like to have a close match. Again stopping it is more important.

        how long has it been doing this?  I have an issue with a section of mine where faint circles form kind of like what you are describing but then after a while they pop off.  so I get little tiny circles of missing gel coat.  as far as I can tell it is from moisture in the manufacturing process.  if yours are not going to that stage then probably something different causing it.  mind you it could still be moisture just not to the degree mine is.  is it localized to one area or all over? 

        did you try take a picture showing it with your phone?  if so you can upload that to this thread, right now we are all pretty much guessing 

        does it look like this (I found these pictures on the net)

         

  • Going to assume this is gel coat fiberglass with decals.

      I think I responded in the wrong place. First time asking questions on a forum. Is there a DYI product out there? It's a somewhat small area. Stressing because I don't know if it will cause damage.

      Yes, there is a area about half the size of a volleyball that looks like a clear coat issue. Thin layer of something is peeling. Not chalky. Being that it's not actually paint I guess it's not clear coat? This area was exposed to the sun for awhile.

        Sorry, it didn't register until now. Gel coat, is there a DIY product out there?
