As I am sure many of you have noticed, our business car, P&R #10 has been looking pretty drab the last couple of years. We discovered a process for tuning it up that doesn’t require much labor, and so far, is holding up well.

Here is the procedure:
1 - Clean the surface with Allback linseed oil soap and let dry.
2 – Apply Viking raw linseed oil (apply with a rag and not a brush).
3 – Dry wipe the surface after ½ to 1 hour later depending on conditions. (Sun, humidity, etc.)
4 – Spray on linseed oil soap EXTRA. Viking says to make this up yourself as all the ingredients are readily available:
1 gallon of hot water.
1 cup of linseed oil soap.
½ cup of Ethyl alcohol.
2 – 3 oz. of boric acid.
This will prevent mildew.

Allback products are available through Viking.

Kelly,

Wow, that's quite a difference. Looks really nice. Couple questions: Is that process removing the oxidation or masking/sealing it kinda like Armor All? What kind of paint is on the car? We have a locomotive with oxidized Imron on it that could certainly use a treatment like that. I can attest that it's tough stuff. We've tried buffing it but the paint isn't very smooth, like orange peel, and would take a year of Sundays and gallons of rubbing compound to get it to look splotchy at best.

Thanks,

I recall reading that the Pullman Company regularly "oiled" their cars between repaints, to restore gloss, the "oil" being linseed oil. Sounds like about the same process.

Looks nice, and doesn't leave materials on the surface (like waxes) that will interfere with future repaints.

I have no idea how it works, I believe that it was the Viking salesman how suggested that we try it.

The paint is Interlux Brightside Polyurethane.

It sure looks a lot better! One word of caution, Linseed oil on rags is highly prone to spontaneous combustion. Use proper care of rags and waste when ever working with linseed oil.

Kelly -

In the procedure you listed, how long did this take? Was it all done in one day? Also, spraying the formula at the end; spraying with what and how heavy?

Thanks.

I find linseed oil to sticky for a long time. Is the linseed oil soap also sticky?

Kelly -

A couple of additional questions:

Done in one morning. One person? Two? More?

"2 - 3 oz. of boric acid". Is that 2/3rd of an ounce of boric acid or two 3 oz. containers of boric acid or 2 to 3 ounces of boric acid?

We are considering giving this a try on our Pullman troop sleeper, but I want to make sure we have everything right.

Thanks!

Les,

It was done in one morning with four people. If it wasn't for all the rivets, it could have been done in half the time.

We didn't get to the "spraying on linseed oil soap EXTRA" yet, so I'm unsure how it is sprayed on. I assume that "2 - 3 oz. of boric acid" means 2 to 3 oz.

Note that Viking linseed oil isn't the same as the linseed oil you buy at Home Depot. I wouldn't try this with any other brand of product.

The soap isn't sticky at all, it's just - soapy. Washes of rather easily with water.

More on what Kelly said - the 'boiled' linseed oil you buy in hardware stores isn't really boiled much, if at all. It's chemically treated to act like boiled but falls short. Allback boiled linseed is actually boiled just like in the old days. Way better product IMHO. Falls into the 'you get what you pay for' category.

Kelly - without looking back at old posts, are you using linseed paints/varnish on the coaches?

It's a shame that Allback wants to be able to advertise that they are "green", so they don't put any mildewcide in their products. It appears the soap and boric acid wash is an attempt to add some after the fact, but note you have to supply your own, which keeps their hands clean for the European market, I guess.

I wonder if boric acid can just be blended into the neat oil? Years ago I'm sure there was enough heavy metal added to either the oil or drier than mildew wasn't a problem.
