Martin,
Thanks for YHO. ;-)
I want to use the POR-15 for the permanence. I am sure I will not want
another color beyond Gloss Black.
My greatest concern is additional heat retention, based on something I once
heard, BUT... I've used this stuff. It goes on thin, the manufacturer
recommends two coats at 1-2 mils per coat. I know of a lister who powder
coated his block. This would concern me for heat retention, it's a plastic
coating.
I guess I am fishing for horror stories. I've already heard a guy I know
say he knew someone who had a brother, etc, etc, who used POR-15 on a block
and had too much heat retention, but no contact or means to learn more.
There may be something intrinsically weird about POR-15 though. That's what
I want to know. I share your concern over heat retention, but don't have
good reason why.
Thanks again,
Jack
