For the future if you use cohesive elastic wrap instead of tape (commonly sold online at vet supply places) it only sticks to itself and leaves absolutely no residue...its even reusable if needed. A $3 roll of it would last you a whole season and it comes in camo if thats what tightens you screws.
Sold under the name 'vetrap'. Scroll down to the color hunter.
