JB Stik Epoxy Putty
JB Stik is a non-shrinking epoxy putty that turns rock hard and repairs steel, wood, aluminum, PVC plastic and concrete.
JB Stik is best if used in conjunction with a 1/4 inch Sliding Door Track Rail Cover to fill in any dips in the existing roller rail so that the new 1/4 inch Sliding Door Track Roller Rail Cover will be supported in the dipped area.
Put the cover on, product feels like Silly Putty, and form it in the dips so it supports the new cover.
Sets up in 5 minutes and cures in 1 hour. It is also sand-able and paint-able.
