NOTICE: When retaining compound or threadlocker is used on carbon fiber surfaces, adhesive primer must first be applied. 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.
