Replacing a Damaged Siding Panel
To remove a damaged panel, insert the hook end of a zip tool 
between the damaged panel and the panel above. Pull downward. 
This will allow access to the damaged panel’s 
nail flange. Remove the nails securing the panel. 
The nails may be allowed to stay in the wall if they are driven flush 
with the substrate after the damaged panel is removed. Remove 
the damaged panel and install a new panel. Then use the zip tool 
to lock the new panel into the panel above.
Replacing a Damaged Outside Cornerpost
Remove the face portion of the damaged post by scoring along 
the outside corner of the receiving channel with a utility knife. 
It may be easier if you first cut away part of the face of the 
outside cornerpost to get better access to make these cuts.
Remove the nailing flanges from the new cornerpost by scoring 
and bending until the flanges snap off. Be sure to score along the 
inner corner of the receiving channel.
Lap the partial receiving channel of the new post over the partial 
channel on the remaining nail flange. Pop rivet the two receiving 
channel legs together as needed.
