Amazing Stuff!

[pgerhardt]

I found an old box of distributor parts which are perfect for another test. Here is a "before" picture.

BTW it looks like I have at least three different types of distributor shafts: two pieces with a ridge at the top; one piece with the ridge; and one piece without the ridge. So here is the model A knowledge challenge: Put these in chronological order!

I have now added the "after" picture.

The one pictured at the top, is the stock two piece that should be used, IMO. The second two, which I also have, are after market one piece and do not provide the 'give' that is needed. There are also OHV one piece shafts which are one piece and out of necessity are of long length.

And, yes evaporust can/is used in any metal rust situation...including gas tanks. Usually, IME, evaporust does a better/best job ....the longer it is allowed to contact the rusty stuff/parts. There is a thread over on the early V side where a 'test' is done...rather scientifically and same results that I have with this stuff.
I recently plugged up a V12 block water jacket openings (after getting all rust out that I could on an engine 'rotisserie' . Poured in evaporust and left for week/two....Emptied out evaporust into containers to use again. Block was amazingly clean and what remained was 'converted' to black oxide/whatever. Very good stuff, and safe it get on hands and environmentally safe to water plants with...if you care,eh
