Glyptal & best way to apply it?

Sometimes I put more effort into it than others. It’s always a good idea to open up the drainback holes and drill a couple extra.

I did that. Once.

Once the oil is covering the block the paint doesn’t make the surface any slicker to aid in oil return.

I have never ever seen anything published that says otherwise.

And since 1980 I’ve never ever seen an engine just **** sand or anything else out of a casting that did any damage.

I say you are wasting time and money.
