• NOTICE: When retaining compound or threadlocker is used on carbon fiber frames or components, adhesive primer such as Park Tool AP-1 must first be applied to all component, fastener and frame surfaces. Failure to do so could result in permanently bonded parts.
• CAUTION: Some painted surfaces can be sensitive to threadlockers, retaining compounds and primers. Test first on an inconspicuous area to see if it causes a stain or discoloration. Clean off any excess from painted surfaces immediately.
