Bulge in exterior fiberglass...

I wedged a board from my basketball post to the rv. Worked.

Yes, that become a thing for me...always get extra now in case someone else needs something and there's no RV place in sight. It's great to be able to say "I have that!"

The delam fix...ha...that's exactly the image I had in mind...couldn't think of any other way that could be accomplished. That should be fun finding a place where I can do that. Adventures in RVing. Good to know tho, thanks!

It's drying...slowly. Seems well bonded to the roof, I think the alcohol helps with that, but time will tell. I will report back in the coming months so we have a definitive answer.

Appreciate all the input!

When I had minor delam issue I drilled a few small holes and injected a epoxy made by West Marine - delam is common in boats and this was the method proposed by the boat expert I talked to. Once the epoxy is injected you need to press the RV skin tight against the rig and let set for a day or two - your rig has smooth skin so a piece of plywood held in place by 2x4 wedged against wall might work. Worth a thought. The tiny holes where the epoxy was injected can be cosmetically fixed with finger nail polish.

This is the main reason to wait for the desert to do the whole job. Not only will things dry faster, but you'll be guaranteed a very good bond to the rubber roof (assuming it's clean.) Dicor will not stick to a wet surface.

A little wider nozzle would be a good thing. If you have some electrical tape just wrap the tip of the nozzle well with it when you are done. This will keep air from getting to the Dicor and it should be just fine for a year or so. I've also learnt to always have a spare tube in the rig for those just in case emergencies. If not for your rig, then for the neighbor that comes knocking on your door in the morning after a night of rain.

Your application rate is fine. As long as there is enough caulk on the joint ti make a seal, all will be good. When new from the factory, the sealants are applied with a pressurized gun and hose. There are huge amounts on all the sealing spots. That may be why folks think an excessive amount of sealant is necessary, they are trying to replicate factory installation amounts.

To keep caulk fresh in the tube, eliminate any air to the tip. Small balloons work well. Refrigeration is a plus.

Theory is remove the tape, remove the screw and the tube is usable again, doesn't always end up that way, sometimes I need to stick something longer than the screw down there to bust through any hardened stuff, depending how long the tube's been sitting.

Cap the tube and put in a seal a meal(vacuum) bag for the longest "open" shelf life.

For the roof vent you mean? Just leave it, nothing wrong with what you've done.

Good to hear. It was very wet last night and it's got a skin on it but it's still reallly soft. If I add more I'm guessing I should wait until it dries really well -- would a blow dryer help? -- then clean again and reapply? Sunny and windy today. Hoping that will dry it out. Humidity is at 60% but might drop a bit as it warms up.
