This is what my machine shop says too, and they have tried everything else.


Yeah I've tried grease and oil and lube sprays and other protectant sprays. Finally just decided that cheap engine paint is the easiest since the blocks always get hot tanked again before the shop starts the rebuild process. When I buy a block now I take it apart, get it hot tanked and then spray it with cheap paint.
