Bowlus Maxi Gap Seal Tape

Overview
This tape was created by Michael Bowlus.  It has a great reputation as a fantastic gap seal tape.  Like the 3M tape this is polyethylene tape.  It is extremely stretchy which allows it to follow the complex curves around the leading edge of the wing root on my Ventus b (although no tape can form to every curve).  This tape utilizes UV protection so that is lasts longer in the sun than other products.  That is very important for gliders that remain assembled for long periods of time - especially if they sit in the sun all the time.  The tape is designed to stay in place and not split even when you take off from an airport with high temperatures, fly at high altitude in low temperature environments and land back in high temperatures.  Also the Bowlus tape is a brighter white than the 3M tape.

I started stocking and selling this tape because Carl Herold told me that he prefers Bowlus Maxi Gap Seal Tape to the 3M tape because it lasts longer before cracking or splitting.  He keeps his Nimbus 3DM assembled for long periods of time - sitting out in the sun.  The UV protection seems to increase the life of the tape.  He believes that the 3M tape ages more rapidly.

So... Bowlus Maxi Gap Seal Tape is better than the 3M polyethylene tape, and much less expensive.

Note: No gap seal tape lasts forever.  All tape will crack or split eventually.

Note from Mike Bowlus on Cleaning Tape Residue
"Any adhesive residue should always be cleaned up with lighter fluid, never MEK, acetone or lacquer thinner.  Lighter fluid will not harm paint, gel coat or canopies.  Never get anything near any airplane that will harm the canopy!  I have heard of guys dropping a container and having lacquer thinner splatter on a canopy, NIGHTMARE!"

Telescoping
Telescoping is the unavoidable tendency for rolls of tape to become skewed over time.  It is caused by internal stresses that are built into the roll during the manufacturing process.  It can be made more extreme by subjecting the rolls to heat or dramatic temperature changes.  I do my best to insure that the rolls telescope as little as possible.  I keep the boxes of tape in my cool basement.  You would think that would keep the rolls from telescoping - but it doesn't.  Some additional telescoping can occur during shipment to the customer - especially when shipped during hot weather.  The good news is that although the telescoping makes the rolls look less attractive, it does not affect the performance of the tape. 

Review by Non-Glider Pilot
"I received the gap seal tape the next day - it works wonderfully!  I am using it on my Varieze - a very slick powered aircraft - and it gained me ~ 5kt in cruise!  Thanks again for your prompt shipment and excellent product." - Kevin Alons, KC-135R (formerly F-16), Varieze

Important Safety Note: "Gap Seal Tape" is Not Designed for Use on Control Surfaces
This stretchy plastic tape is perfect for use sealing fixed gaps - such as the gap between the wing and fuselage.  I do not recommend using it on control surfaces such as the gap between the wing and aileron or the fin and rudder, or the horizontal stabilizer and elevator.  Plastic tape will shrink over time and especially when it gets hot in the sun.  If it is connected to a control surface it may contract over time and not allow full travel of the control surface.  Or as it gets tight it may pull off as it is stretched by the control surface - which could lead to high drag or reduced control of the aircraft as the tape flaps in the wind or changes the airflow over the control surface.  Using plastic tape secured on both sides of a control surface gap is unsafe and may be an illegal modification to the aircraft.
