Don't do it !!!

I've been scraping silicone off my Silver Olive for a couple months (little at a time - especially in the heat). It has definitely damaged the aluminum: fairly heavy corrosion/deterioration under the bead/length of silicon where applied. Now I have permanent grooves along many of the seams, above windows, above the awning and around the vents. Nice.

Rivet Dreaded Silicon Caulk - Boo Hoo

OK....now what and HOW??? Last fall, during winterizing, a camper center "caulked" around a vista view per our request. They used clear silicon and pretty much smeared it along the top of the window frame where it sets into the shell.
When re-caulking, I believe you should remove the old, dried/cracked caulk (even though a tour guide at JC said they would just caulk over it there!) If so, what tool (dental pick?) would you carefully use. The exsisting caulk is white in color with a sort of grainy, rather than smooth finish, is to all windows, door, rub rail, in a perfectly applied 1/4 " line.

Thanks a bunch, Sue
(oh, and volunteers are welcome for this project!!)

I buy Sikaflex from local RV dealers. Most don't carry Vulkem.

Harbor Freight has a nice little dental tool kit that comes in handy for removing the old caulk. Sounds like you have Vulkem/Tempro around your windows & doors. If you aren't experiencing any leaks, you don't really have to redo it, but the tools come in handy if you have to remove it. The silicone is a pistol to remove. My trailer was covered in it when purchased. I didn't have many fingernails left & used the dental tools to death. It's just a time consuming tedious job. No special tricks, just time!

Thanks Becky. The rain water is coming out from the two side windows that are across from one another and dripping on the "ledge" - Vista View windows above. Of course, there's no easy way to determine where the water is getting in.

Does anyone know if there's a "safe for Airstream" solvent to remove the silicon? Grrrrrrrrrrrr!!

We use popsicle sticks, sharpened to a point to remove old caulk from the cracks. This gets most of it off, then we use chemicals to get the residue that remains - PermaTex Gasket Remover works pretty well on %#$@*! silicone, but be sure not to get it on any paint or plastic it'll take that off too...like Aircraft Stripper - it burns your skin so be careful. We then rinse well with water and final clean-up with mineral spirits...then re-caulk with Parabond & Vulkem - Parabond for small cracks like most panel joints & Vulkem for bigger gaps like around window frames, eyebrows and openings.

What does everyone use if you want to seal between the glass and frame on the exterior? Mine old seals are leaking and instead of taking the windows out to replace the factory seal, I've been cutting and removing the old seal around the frame. Then I've run a bead of Vulkem. I thought I had seen this method on one of the posts. Will this work?

Ken.

Vulkem or Sikoflex does a great job, resealing the glass to the metal flange. Nothing to take apart.

Thanks for your handy dandy, tried & true method of removing %#$@! silicone. Is PermaTex easily found? This and the mineral spirits won't harm the clear coat, huh? Cool!
I think I'll get a box of sticks and see if the grinder will give them a satisfactory point.
