Discolored Basement Storage Door

[higgs6867]

Was wondering if anyone had seen this before and might know the cause. The curb side basement storage door is discolored on the bottom left hand side and also a little on the bottom right side, the discoloration does not come off, it appears to underneath the clear coat, possible moisture issue? At first it was no big deal since it was very small, now it's growing and looks gnarly. Any ideas?

Have not experienced that; first guess would be a moisture issue although I dont see any delamination from the photo.

No there is no delamination that I can tell, no distortion at all, door is solid and functions as it's supposed to, it's like a fungus or something, Here's a shot from the other side of the same door, this discoloration wasn't even there a couple of weeks ago.

Odd. Will be interesting what you discover.

Does it appear to be on the outer surface or could it be behind the Gelcoat, looks like it might be glue that has somehow leeched out between the Gelcoat and the fiberglass.

Never seen that before, will be interesting to know the reason.

I have the same thing on both bottom corners on one storage door. At first I thought it was grease from my hands, nope. Tried everything I know to remove with no luck (wax, cleaners, borax, etc.)! Thought it was something I did! Now I see someone else has it also. Anyone else?

[higgs6867]

Well like I said it's under the gel coat, no wiping it off. I guess I could send the pics to Keystone and see if they have any clue. Could anyone direct me to the appropriate person or persons?

Looks ugly, be interested to know what you learn

I have the same thing on my drivers side storage door.
Please let us know what you find out about this stain.

Looks like it will have to be replaced. Hope Keystone steps up (warranty or not) and replaces it for you.
By the way, nice truck, I have the same model and color combo.

[higgs6867]

Well, Keystone has agreed to replace the baggage door at no cost to me. I think they were intrigued by the photos I sent them and want to investigate this more closely.
