We then bored the 4 bolt holes using an oversize 15 mm bit to allow for coating with slightly thickened resin bringing the diameter back to 12 mm. To do that we used 12 mm bolts wrapped with adhesive tape to keep the resin separated from the steel. You could see the tips of the bolts protruding from the hole
Finally, we sanded and cleaned both sided in preparation for painting.
