J-roller (for pressure activation)

This is non-negotiable for Eternabond: you need a J-roller to pressure-activate the tape. Darren specifically called out that rolling is part of what keeps it from peeling later.

Pros

  • +Pressure-activates Eternabond for a stronger bond
  • +Helps eliminate air pockets and edge lift

Cons

  • -One more tool to carry/buy
  • -Requires firm, thorough rolling to be effective
