Long Strand Filler
Polyester filler is reinforced with long, interlocking strands of fiberglass to create waterproof repairs to holes that are up to one inch in size.
Long strand reinforcing produces repairs that are twice the strength of ordinary body fillers.
Ideal for filling gaps and joints that flex.
Can be used in conjunction with fiberglass tape, cloth or mat to repair and rebuild rusted-out metal or damaged fiberglass material.
