I was looking at old posts and it says about applying a liqud mask, what is that?

Well I know Micro mask is one kind .A mask that you apply to keep from painting over something you want either to stay clear or another color but remember that it is water soluable so would not use it with acrylics as spraying might wet it and make a mess. I think mostly Ac people use it. I myself use fisket film or low tack masking tape

Howdy Sancho,

sgtreef is correct. AC modeler's mainly use it. But it obviously can be used for any modeling purpose. I've got some made by Bob Dively, decent stuff. It's mainly used for areas that are difficult to impossible to 'tape' off (complex curves, compound turns).
I personally wouldn't suggest AB'ing it on, unless you don't like your AB much.
Apply it with a brush. Make sure the coat, or coats, are thick. It's a bear trying to get off thin coats, you generally wind up 'rubbing' it off, thereby affecting your coat of paint.
A hint: If and when you do use it, you can brush it on fairly sloppy, then use a #11 to cut your fine edges and remove the excess. Viola! You have a nice masked area with a nice sharp edge.

Tread.

For the record, I almost never use it. I, like sgtreef above, use either Frisket paper or automotive body-shop grade masking tape. (this is masking tape developed specifically for painting!

I used liquid mask to cover the tire areas on the wheels of my Topolino. It worked pretty well. To remove it, I found the easiest method is to use a piece of masking tape. Stick it over the area with the liquid mask. When you lift the tape, the mask should come loose and is much easier to remove.

So you actually have to buy a special liquid mask, you ca't use like rubber cement or anything you can find around the house?

I would gues you could use any thing that alows you to do the folowing....

doesn'r ruin the surface its applied to( fog clear parts)

can be cut using an xacto knife to remove excess without rising off prematurely

and last will not bond to suface it's attached to or or newly painted surface.

IF it does that give it a shot on a test piece first, I think however it's worth the couple of bucke for a bottle and it lasts a long time.

It's always good just to keep in stock on the bench.
There are time's you will find it comes in handy.

liquid rubber can do the trick also, but it may be more agressive to underlaying paint or to clear parts. If you have rubber on the shelf, it's certainly worth trying on a piece of clear part. If it doesn't get foggy, you may well do without (the more expensive) liquid masks.
I don't know about shelf life, but I have a small bottle of liquid mask that sits here since forever. Still works well...

Be careful when using it on top of paint. I tested a couple brands of liquid mask on top of a coat of acrylic paint that had dried for over 3 weeks and it pulled everything off down to the plastic. What I was trying to do is make some realistic paint chips but it didn't work out. Someone told me that using rubber cemnt for this will work for this but I have yet to try it. The liquid masks work O.K. on aircraft canopies but I found it to messy to be accurrate enough for this.

Hi,

Sorry for joining the post late !

I found an article at this link which explains how to use Liquid Latex as a masking tool for developing Aircraft camos.

Take a look, it may help ...
