  • Note: for best adhesion, first clean the surface with mineral spirits, then use an alcohol wipe to remove mineral spirits essential oil residue; Place the rolled J-channel in the sun for half an hour to warm up, then unroll it and keep adjusting its position until it's flat before applying; Place the J channel on and press firmly for 30 seconds to allow the adhesive to set firmly; Application in hot weather or without preparing the surface may result in poor adhesion
