## Questions & Answers

**Q: Does the black caulk dry to a gloss, or is it more matte finish, like a dull rubber?**
A: it still retains a dark matte color I would not say dull, but not a gloss finish

**Q: Will it bond to bare aluminum to seal around the rivets?**
A: Yes, I used it to seal my roof fans on my Sprinter.  It adhered to painted metal (scored the paint), wood framing of the opening, plastic shroud and aluminum pressure plates.  I am extremely satisfied with this product and from the day installed, it shows no wear even after a year.  Excellent product...  Another really good product is 3m 4200 Marine Adhesive...

**Q: Will this bond to rubber?**
A: Not sure about rubber, but everything else I happened to get it on and let dry it stuck like paint.  My clothes, stainless railings, fiberglass cabin, teak of course, cork fishing rod handle, my leather wallet. . .

**Q: can you use to adhere spoiler**
A: probably work great
