The block is cracked above the pan rails, but we're going with it because a) it's free as I already have it, and b) it didn't use so much as a tea-spoon of coolant before.
While the block is clean and dry, I thought it a good idea to use the Irontite Ceramic sealer, then afterwards use their All Weather Sealer in the coolant. If that plan fails, I can chuck in loads of K-Seal like the previous owner did!
It now becomes clear as to why you are using the product that you selected.
