My 1925 Chev Roadster after a Molasses Bath

Before

After

 

damn that came out good. I have a 27 T that needs to be done. How long did the process take and what was all involved ? details if you can

 

Damn i was skeptical of that before that looks pretty damn clean!

 

Looking good Jimmy. Keep at it.

 

WOW!

That came out nice. give us some details......

 

yes please. more details

 

Geez...how much molasses and how big a tank did that require

 

Hell yeah, I was thinking the same thing. Or can you apply it like stripper and let it set on the surface.

Sure does clean the metal nice.

 

Papa Mole, Mama Mole, and Baby Mole were following each other through the mole tunnel. Papa Mole stops and sniffs the air: "I smell turnips." They go a bit further and Mama Mole stops and sniffs the air: "I smell turnips, too." They go a little bit further and Baby Mole stops and sniffs the air: "That's odd, all I can smell is molasses."

 

I use 5:1. When I did my 40 dash, I made a temporary trough with a basic wood frame and lined it with some plastic sheet. Was only deep enough to keep the dash under the liquid. Covered it with some board and left it a week, gave it a scrub, left it another week and what was the colour of Jimmy B's firewall came out spankin' new! I treat things with a metal prep solution straight away to prevent the almost instant flash rust. I use Ranex, Jimmy might know it.

 

I used a 7:1 water to molasses mix in the blue 44 gallon drum in the pics.

The cowling I dipped in this.

Make sure not to use black plastic, use the pond liner that you get from the hardware or landscape suppliers as it is rubber and will cop alot more abuse, also use some old rubber floor mats to protect the bottom as you don't want to cut the liner as it is not cheap cost me AUS$60.
I left the cowling in for 10 days, usually you leave it in for 14 days.

this is after 5 days. The surface rust wasn't as bad.



When I was searching for info on this process I came across one guy who built a tank big enough to dunk a T roadster body Now I can't seem to find it, go figure
Cheers

So ya dig big hole in the ground, line it with plastic and fill with molasses. I bet all the critters in yer area have a lot of cavities in their teeth

 

I didn't know Mole-asses worked so hard....

 

G'day X38, where did you buy Ranex from? I just sprayed my cowling with WD40.

 

The cheapest place to get molasses is the feed store.

 

I get Ranex from Bunnings usualy. I think it's full name is ranex rust buster. It's phosphoric acid based, leaves a good surface, keeps rust away for a long while, especially if you can keep your hands off!

 

That looks awesome! Question, though--and I'm not trying to hijack this post BUT: isn't that a Dodge front cowl? I've seen those before, and everyone always said they were Dodge. Just asking.

Thanks,
Theo

 

Thats a chevy cowl.

 

I used RS-!, which I bought from the local auto paint store. My stuff came out of the tank about 12 months ago, and there's still no rust.

You just can't beat a good bath!!

 

Ok, maybe this is a silly question but does the molasses come as a liquid, errr gel, or is it some sort of pellet? Live in the midwest in the boonies but never messed with molasses from the feed store! Looks like a good way to strip though.

 

Sweet!

 

sweet Roddinrod was faster.

Very nice job. From the looks of the before picture I would expect the body to be pitted but the after picture looks very smooth. It looks like a great start with a body that smooth.

 

Wow you could sell that service now that you have the setup! I have a banger block to dip please.

 

Pun intended?

 

Anyone know if the molasses effects aluminum ? I have an old flat bottom boat that would make a good tank (no seats), but it would suck if the molasses ate it up and leaked out....

 

I have a Model A tank I did about 1 year ago in my shop, No oil, no primer, it hasn't RE rusted yet. Don't use a blue tarp, eats holes in minutes. Yum-Yum

 

This one? http://www.stovebolt.com/techtips/rust/rust_molasses.htm

Does it strip the old paint off too?

 

heres an explanation for all of this...I think
Rust Removal Using - Soda Pop?

When I was about 12 years old and just getting interested in engines I heard my uncle swear that he got a stuck piston out of a motorcycle he had by using bottle of Coke. It had set out in the yard all winter and had rusted up inside. But we all know pop is sticky, water based and wouldn't itmake a worse mess? After all, Mom always said "don't spill your pop, it will make everything sticky".
As I grew up and got interested in cars and motorcycles myself I started to hear of other such "urban legends" and decided, hey, maybe there is something to this. The people that said it worked were quite insistant, and there sure was no proof that it did NOT work. So I decided to investigate. (amazing what little it takes to entertain me)
So here is what I've found - many carbonated beverages will remove rust. This is because the gas used, carbon dioxide when mixed with water, makes carbonic acid. To make rust, the iron oxidizes - it combines with oxygen. This is why rust is also called iron oxide. The carbonic acid reverses this reaction - this reversal is called "reduction." Here's a better reason - take a look at your Coke can - it has phosphoric acid as an ingredient. Phosphoric acid is the basis of Naval Jelly, a commercial product used for rust removal. Phosphoric acid dissolves iron oxide very quickly while etching metallic iron very slowly so you can leave metal in phosphoric acid with little damage.
The downside is that all acids contribute some hydrogen to the metal structure, weakening the steel by hydrogen embrittlement - so always use only as much time as is absolutely necessary to remove the rust. An advantage of phosphoric acid is that it leaves a fine protective coating of iron phosphate. Because this coating is not thick or durable some protection is still required. Years ago supposedly Volkswagon use a process of phosphating metal prior to painting as it provided a chemical protection against rust under the paint layer.
So, spilling your Coke into your old engine wouldn't really be a bad thing if you were trying to remove some rust.

The body looks to be in pretty good shape. Though I don't know so many english terms, what is a "Molasses" bath?

 

I thought for sure that you would have said that you applied it with a biscuit.

Did the Bees hang around?

Looks real good!!
