Unfortunately that's the smallest quantity they sell. It works great though. Here's a side by side on my heads. 2 applications of PJ-102. Let sit for about 30 minutes, rinse with cold water. Cleans and passivates. YMMV.

Flat honing stone is all that is needed. Knock down the high spots left by prying and banging things around. the critical area is the fire ring. Imre is right to keep it lubricated(water is fine) . Place rags in the cylinders and apply a ring of grease at the top of the cylinder. That should catch any aluminum filings (there won't be much at all). Pull each rag and clean out the bore before rotating the crank.

Also, to clarify on the PASA Jell 102, it cleans the staining and any microscopic pitting corrosion (as well as larger pits), but obviously does not "smooth" the surface. That still has to be done mechanically via scotchbrite, or a sharpening stone, or whatever your preferred method is.
