Apply the Park Tool Adhesive Primer as the first step in prepping surfaces and accelerating the curing process for component installation and fastener use, such as applying a retaining compound or threadlocker to carbon frames. Please note, you'll need to use this with Park Tool's TLR-1 and TLR-2 Threadlockers or the RC-1 Retaining Compound to prevent permanently bonded parts. It's common as a first step application in installing PF30 bottom brackets and pressing bearings into carbon fiber frames.
