great caulking
I have used DAP brand caulking products for years in my business and this Dynaflex 230 was recommended to me by a fellow remodeling contractor so I ordered some. I will be using this caulking on most projects going forward. It applies easily and cures well. The variety of colors is great so that you can match the caulking to the job.
