Hi, I have jet washed my engine block ready for machining and will if I can get my new Clarke Blast Setup attachment working try Soda blasting it.
What Etch Primer should I paint the block with after it’s been machined (or should I paint it before hand).

For the Top Coat I guess an engine enamel, unless anyone wants to recommend anime thing else.

As far as colour, it will be a 1293, so it will either be red or I have seen a few nice looking black ish colours - what do you reckon?

You can just use standard aerosol or 2k brushable paint. It's all I use on my engines, the only time you'll need VHT is if you want to paint the inlet manifold

Just use a piece of scotchbrite or 150 sand paper and you can then simply prep clean and paint the motor. I wouldn't media blast it for various reasons

I'm pretty sure I just wire brushed my block and painted directly with this stuff https://www.ebay.co....l-BMC-MOWOG-Gre, Goes o well, they sell other colours as well.

Warm the block with a hot air gun before you prime/paint it for a longer lasting finish.

engine enamel goes onto bare metal no need to prime

A spray can of high temperature engine paint is cheap enough. Remember to paint the inside of the block with red oxide primer.

Inside the block? Do you mean the area under the cylinders?

[jonny f]

Why on earth would you paint the inside? silly idea!!!! Do not do that.

Not sure red oxide is the right paint ... being more of a primer is it likely to still let the oil through .. the one above from frost's is

I recommend POR engine enamel: https://www.carbuild...ne-paint-42268  really, really good stuff.

I have used the POR stuff which is great, unfortunately they didn't do it in the colour that I wanted so after advice from my father, got some 2K mixed.  Brushed it on.  It looks great!
