Dap 10.1 Oz. Gray Advanced VOC-Compliant Exterior Gutter & Flashing Sealant — Residential Use, Standard Application

I was blessed to receive a lesson from my father, a British trained journeyman carpenter/cabinetmaker. Roll it in your hands to soften it. That's the most valuable lesson. It's an art form, a bit like golf, the more you do, the more you'll love the exercise. As a pro heritage restoration painter, there is no other choice on the market. Also makes a great filler for nail holes & joints on interior trim. One just needs to take care like any pro should. Not for amateurs who can't recover from a mistake.

At first when I was trying to figure how to use this product I got easily frustrated and didn't want to do the job anymore. Although I kept on going and was able finish 10 windows in 3 days. I found it easier to use the putty with latex gloves on because the putty doesn't stick to your hands and it helps you smooth it out. At first I was using a wide putty knife but that didn't work good because it was hard to work in the corners and places like that so I bought the tiniest one they had probably 5cm wide and went to work and it turned out great by the end in my opinion for a first time user. I found when I left the putty in the sun it made it stickier and easier to smooth out. Dry time on the container says 7 to 14 days so you have to be patient with this product. After 3 days of sun about 20 - 28 degrees celius its has a harder top layer but is still soft.Overall I liked this product.
