Finally a kit that actually works
Size: 21pcs, Size: 21pcs
Tried the small nail on a pinhole leak, held pressure for 2 weeks now. The screwdriver feels solid. Comes with 3 glues which is generous.

Beats rope plugs every time

Used plenty of plug kits. This screw-in type is faster, cleaner, and no arm workout. Large size seals a real nail hole tight. Trunk ready.
