Enrique, when you take your block in to have the bearing faces and cylinders=
bored(if necessary), tell them to dip it in their tank or have it blasted=
clean in their pressure wash. The machine shop will put a special chemical=
onto the block which cleans all surfaces very well, as well as removes any=
paint. What you get back from the shop, you will have a nice, clean=
surface ready for primer. The apply your engine paint, and voila, a=
magnificent job. =20
I would discourage the use of sandblasting as a means of removing paint from=
an engine block. The chance of sand getting into the recesses of the block=
are too great. When you rebuild the engine and start up the car for the=
first time, those little sand particles will be floating around possibly=
eating up your critical surfaces and ruining all your work. =20
Chemical stripping is possible at home, but I did not have the chance to try=
it out. Normally, though, chemical stripping is easiest on smooth, flat=
surfaces, but it may work in crevices of an engine block. I dunno!
