With the time coming nigh to insert the aluminum frame in the FRP hull for the final time I started checking all my previous work, cleaning the parts labels off and torquing and marking all the bolts. I used Varsol paint thinner, a thin bladed spatula, the scouring pad that came with the KeelGuard and a cloth to do the clean up and they worked well on both the aluminum and FRP parts; removing linseed oil, labels, torque seal and red marking pen without scratching either the aluminum or the FRP gel coat.
