Gtechniq PW Panel Wipe Removes Oils and Residues to Prep Surface - (500ml) Gtechniq PW Panel Wipe is specifically formulated to remove oils and other residues from surface, prepping them for any coating application! Many times polishing oils and residue can negatively effect the way sealants, waxes, or coatings bond to the surface. PW is designed to remove all these oils and residues so that semi-permanent coatings, such as C1 Crystal Lacquer and EXOv2 Ultra Durable Hybrid Coating, can form a durable bond with your vehicle's paintwork.
