Painting non-paintable caulk
I went to my in-laws to paint stain on some new cedar siding they had put on their house only to dicover that it had been caulked with non-paintable caulk. Is there any solution to this? I think I can sand some of down, but the joints between the siding and the trim are a problem. Will putting a primer on first help. Any suggestions are appreciated. Thanks.

Silicone caulk is generally unpaintable. Nevertheless, I believe you might get reasonable results from priming with Zinsser BIN, a shellac based primer. It will stick to pretty much anything. Then apply two finish coats.
Hope this helps.

The pigmented shellac should work fine. While shellac isn't a good primer for large exterior areas it will be fine for what you need - really the only choice other than removing the caulking. If the primer crawls more than a little over the silicone, apply a 2nd coat.
