1. When installing the panels some caulk may squeeze out of the seam.
2. Remove any excess caulk using a wet rag.
3. Using a wet paint brush, smooth the remaining caulk into the panels. Use a horizontal (side to side) motion to blend the caulk color into the panels.
4. Caulk may also be needed where the screws heads are, apply a small amount of caulk to conceal the screw head. Then smooth out the caulk with wet paintbrush.
