Goop on the bottom, I made a scoop to scrape the crud off the bottom.
Stuck locking strips, PB Blaster and let it soak or slit the strip with a sharp knife and pry out. Older frames see the dip below.
Clean grove out, bent flat screw driver and Scotch Brite pad.
Stencil remover, One Stroke reclaiming powder. We haven't purchased it for a while but remember it was pretty cheap and worked well. One package of powder to five gallons of water.
Old gunk off frames, brake clean but it may remove the coating off the frames.
Gunk off old frames already missing coating or ones the coating is chipping or coming off, dip in a mild mixture of oxalic, muriatic acids and water, same solution for radiators. Dip frames for about 5 min, lightly scrub with a brush and flood with fresh water rinse.
Leaking bolts and old frames with plastic caps, seal washers. They are hard flat washers with a bonded rubber insert that will seal around the bolt and frame.
