Several months ago, in a Mid-Scale Forum thread, there was quite a discussion about the effects of alcohol on Testor's Dullcote. Some advised against using the two together, others said they had never tried it or had had no "problems" when they had tried the two. I mentioned that I thought it was great for modeling hard water deposits (lime and scale) on water tanks and plumbing.
Unfortunately, at the time that discussion was current, I could not find some construction photos that I had taken of my water tank car right after using Dullcote and alchohol. I thought I had deleted them and they were permanently gone. But lo and behold! I found copies of the photos on a zip disk this past weekend!
So, for anyone who is still interested in the topic of Dullcote and alcohol, here are 4 of the pics. The first three were taken after the first application of DC/alky. The last photo was taken after some detail parts had been added and a second application of DC/alky had dried.

Awesome, fantastic, outstanding, just a few of the descriptions that come to mind. Will have to file this for future reference!

Hi Mike
I will echo Tysons words.
Fantastic and whatever else he said.
Never mind the scale deposits it is the rust I like.
Probably the best rust I have ever seen. 
Tell me did you do it with just paint and chalk.
Inquiring minds want to know your secret.

Thanks, guys.
John, I'm not positive about some of this because I just realized almost 18 months have passed since I shot the photos of the water car. But....
I remember airbrushing the tank casting. I think I used Apple Barrel "Indian Red." (It's the same color I used on the ballast car a couple of months ago.) After that dried, I dribbled alcohol on the tank and then dusted it with rust-colored chalks. I remember doing that several times over the course of a Sunday afternoon so that the rust appeared to have layers. I also remember thinking that it was too much and wiping some of it off.  After I had applied the first coating of Dullcote and alky to get the hard water deposit, I painted a slurry of alky and rust chalk directly on the deposits and let it dry. The final step was to respray the tank with Dullcote and then flow some alcohol back over it. What I was trying to get was a blending of rust and hard water scale all within the same texture range.
At least I think that's how I did it....

Hi Mike
Thanks
I am going to put a link to this thread over in the Scenery sticky of the Model Railroad Construction forum.
This is a clinic on how to make a metal surface have a rusty look.

That's interesting Mike!
I made that discovery accidentaly a couple of years ago on an HO layout I was working on.
I managed to get an India Ink & alcohol wash on a plate girder bridge I had just sprayed with Dullcote. I liked the effect, so I didn't bother to "fix" it...
It never occured to me until I saw your thread that it looked like hard water stains...to me it looked like the "scaling" you see on really corroded metal. But I guess chemicaly speaking, it's kind of the same effect.

OOOOH Mike,
That really looks great! I have bungled some work using dullcote and alcohol but, I can see some great useful applications.That has to be the finest rust and mineral deposit work I have ever seen....hands down!!!
I built a Southern Caboose for a friend and was all done and was so proud. I hit it with dullcote and the whole caboose looked like I just took it out of the freezer!! I think, I just re-sprayed it and it was fine...it's been so long ago.

Mike,
Like always, you have given us some great tips. Thanks again!
Your water car looks great! I'll keep these ideas & photos in mind when I do my water car.

Mike,
That rusty water car....I don't reckon it will hold water,it's to far gone.It should have collapsed years ago.
Brillant bit of work,it sets a new standard to aspire to.Another new technique to file away and try at a later date.
Merits an article in the Gazette.

Thanks, guys.
I'm glad some of you might find some use for this. (BTW: I have also used this technique to create mortar lines in brickwork and to create stains on brickwork where lime would have leached out of the mortar over a period of many years. It takes patience, a good quality fine brush, and a steady hand, but it's worth the effort.)

thats the best example i have ever seen of the chemical reaction of alcohol and dull cote, and the best part is you took it tooooooo another level detail and weathering wise...madmike3434

The effect of rust and hard water deposits on the tank are superb!

Thanks, guys. It's hard to believe I built that water car 5 years ago. I need to get back to work on something.... sometimes I think I spend wayyyyyy too much time on the computer and the internet.

The Dulcote and Alcohol really looks great Mike. I am definitely going to try it.
