Entire hull from waterline down was machine-sanded with 600 grit sandpaper.
Afterwards wiped all resulting dust from the hull with a clean, wet cloth.
Because Hull Maxx™️ was applied directly to gelcoat hull here, it was first applied Nasco’s Performance Adhesion promoter (primer) with a rag or applicator.
Afterwards – proceeded to coat the hull with Hull Maxx™️. Just one one step of coating. Remember that!
