Discoloration on propane cover

[Steph and Dud B]

I'm seeing a yellowish discoloration in a band around the top of our propane cover.

Hard to describe, but it looks like the white pigment in the gelcoat is wearing off, leaving this one area slightly yellowish, but still very smooth. The trailer has been washed after each trip, kept waxed, and garaged when not in use. Haven't seen this on any other part of the hull. Tried a bit of wax on this area, but it didn't change. Any ideas?

I'd open a ticket with Oliver. Our 2008 has nothing like that, and it is not garaged.

We had very similar discoloration earlier this year.  We had loaned out our trailer to a relative for a few weeks while she was moving from one house to another.  She had laid our rubber backed doormat on the cover because she didn't care for it.  We used rubbing compound followed by polishing compound and it took care of the yellowing.

Opened a ticket. There hasn't been anything placed on the cover but I could try rubbing/polishing compounds. Thanks.

My doghouse has developed similar yellow areas, mostly where the surface planes transition and along edges. Has only been washed and waxed. Planning to try polishing and buffing to see if it goes away. Interested in what you learn from Oliver

I had something similar happen on an old boat that had been compounded with an orbital buffer one too many times. The gelcoat became so thin that you could see the fiberglass showing through in spots. I hope that's not what is going on with your doghouse...

I hope not either as I have only hand washed and hand waxed since new.

Strange. I need to check ours. I spray it with ceramic coating after washing after each trip. Not seen anything that sticks out, but I will check

Then maybe it's just a coincidence that it happened to ours when it wasn't parked at home with us. The yellowing on ours looked just like your photo.  Before the doghouse cover yellowed, our trailer had only been hand-washed and waxed too.

Seems like OTT has a different manufacturing or finishing process for the doghouse. Interested in their response. Ours looks no worse since our front end gelcoat is quite oxidized, more flat not glossy.

I recently noticed similar discoloration on my 2022 LE2 propane cover. CGI Detailing was unable to fully remove it, but it's not as severe as before.
