This repair string works better than traditional drip repair candles when filing base gouges for several reasons.
First, it's made of harder and more durable polyethylene, so your repair jobs wear longer and don"t "dish out" prematurely.
Secondly, since it is melted into gouges using a base repair iron or pistol tip (see items above) insted of burning with an open flame, no smudgy black carbon particles are created which invariably fall in the gouge and create cosmetically ugly and mushier repairs.
This string is 1/8" in diameter and comes in 10 foot long rolls...enough material to keep most bases patched through a full season.
This material bonds well in both deep and shallow gouges, plus can be applied atop copolymer repair material when making repairs to core shots or along steel edge
