## Questions & Answers

**Q: It says "Apply activator to lead attachment area on window and tab", but then says to not use the activator on the tab. Which is it?**
A: Clean lead attachment than apply activator hold tab on it for awhile until it is holding.don’t plug in cable wire to it for 24 hours.

**Q: Just received this kit and adhesive seems watery, is this normal? I thought it would knead into a putty like adhesive.**
A: I don't recall that it ever got to a paste-like consistency.   The adhesive is sufficiently liquid that it could be mixed up and worked into a consistent color all the while being in the original shipping packet.  I was able to get the tab to attach tightly by coating both the tab and the metal grid with the adhesive liquid.

**Q: Do I re-glue the tab to the same spot as before, or to a different spot in the contact area?**
A: the instructions are with the package, you glue it to a spot where there is conductive material.

**Q: where can i buy defroster tab for my car**
A: They sell them here on Amazon.
