Pre-clean/wash the vehicle according to how dirty it is and dry thoroughly. Depending on the condition of the paintwork, treat the surface with a silicone-free polish and then degrease with Panel Preparation Spray. Spray PerfectFinish Sealant onto a clean Polish & Sealing Towel and spread evenly over contiguous areas. Finally, remove the residue with a dry Polish & Sealing Towel. Do not spray directly onto painted surfaces. Alternatively, the product can be applied by machine. To do this, apply PerfectFinish Sealant to a Polish & Sealing Foam Pad and work it into the vehicle paintwork in sections using a compressed air eccentric or eccentric polishing machine. Finally, remove the residue with a dry Polish & Sealing Towel. After applying PerfectFinish Sealant, the vehicle must not be washed again within 24 hours.
