I found this in the maintenance manual from Hoffmann:

9.1 The paint of the HOFFMANN composite blades is resistant against fuel, oil and nearly
all solvents. The propeller should be cleaned periodically using gentle detergent or
equivalent and be protected with car polish that does not contain silicone. The surface
protection (paint and epoxy fibre glass) should be completely sealed to prevent
penetration of moisture into the wooden core. In special case contact a licensed
inspector to prove the safe operation of the propeller.
9.2 Minor damage (small scratches, etc.) can be repaired easily. Prior to repair check that
the fibre glass covering and the wooden core are not damaged. The materials required
for repair can be obtained from HOFFMANN. Proceed as follows:
9.2.1 Clean damaged area using solvent and smooth it out using emery cloth # 220.
9.2.2 If required, apply epoxy resin filler to fill the bulges. Do not apply too much filler.
9.2.3 Allow filler to dry. Trim the surface using emery cloth # 220 again
9.2.4 Apply paint (white, grey, black or yellow). It is recommended to use original lacquer,
because resistance and bonding of other paints cannot be guaranteed. Observe drying
times if several coats are painted.

Let me know what your prop protective tape looks like. Mine could use replacing, The roll of tape is expensive (I think around $300). Let me know if anyone wants to split a roll. My guess is 1 roll would cover at least 8 props.
