We purchased a stucco home that was coated by Thorocoat 10 years ago. Is is a very coarse/rough finish in a grey color. There are several hair line cracks that have started and I would like to seal them before they become larger. I used a clear silicone caulk on some of them which seems to work, however the silicone is "shiny" in the sun light, making the crack visable.

Any recommendations on a sealant product to seal the hairline cracks without being so visable? (I dont want to paint the house)

Thanks, Dan
