Care and Maintenance Tips

Proper topper care is essential to protecting your investment.  Care for your topper just like your truck.


Avoid the use of paint thinners, scouring and any ammoniac product to clean your pickup truck cap. Benzine can be used to remove stubborn dirt from your topper. Clean the inside of your truck cap with a damp cloth. Your fiberglass topper can be polished regularly, like your truck, to prevent yellowing of the gelcoat (in the case of a white cap) as the years pass. Use ordinary car wax polish for this purpose.

Door Locking Mechanism

Clean & lubricate door lock assembly and hardware. The locking mechanism on a pickup truck cap can usually be adjusted to ensure continuous functioning. If your truck cap has metal end-locks and striker plates, it is advisable to lubricate them every six months with petroleum jelly or Vaseline to ensure smooth operation. This will not be necessary for truck toppers with nylon endlocksor striker plates. End-locks and striker plates can be adjusted if the door is rattling or if the end-lock does not catch the striker plate.

If you have difficulty inserting the cap's key in the lock or operating the mechanism, a
 liberal application of lubricant will solve the problem.
 It is not advisable to drive with an open truck cap door as this will damage the door, hinges and gas stays supporting the door.


All truck caps are (normally) manufactured with safety glass window panes. Avoid loading heavy objects against the cap's windows, as this may break the windows or dislocate them from the frame. The gutters on sliding windows should be cleaned regularly to ensure that windows open smoothly and to prevent blockage of the draining holes that could cause water leaks.
