My present persisting problem is that where the bulb seals are attached to the RV is cracking & leaving long gaps at the top of the seals. I have tried Dicor Lap Sealant several times, but it cracks again in a month or so. Is that caulk or glue or what? What should I use?
The screw should in the bulb seal on one or both ends, stick your finger into the bulb as it may be up inside an inch or so. Once removed the seal should slide off the plastic track. The track has screws the full length so if your having gaps I'd guess the screws are broken off, if so I'd remove the track, clean both surfaces, add some type of sealant under it, probably butyl putty tape & replace all the broken screws. I think there's a specific caulking that seals the outer edges of the seal, but can't recall what it's called.
A fellow RWer here was replacing the bulb seal above their dining slide, but apparently the original owner didn't know how to replace it correctly & glued the seal over the track rather than sliding it on, made a relatively simple job into a big mess getting all of whatever they used as glue cleaned off.
