Using Milluput

[stitchdup]

I usually use auto fillers that go on top of the primer for my models but i've got some milluput to use. Can it be used over primer too or do i need bare plastic? I'm trying to not buy any new stuff just now and to use up what i've already got in stock

It will stick to anything, just remember to have a wet Qtip ready after forming, to wipe off any residue

If you use it to build up the thickness of a part (or on joints between parts), rough up the area where it is to be applied, and make sure those areas are clean (no mold release) before applying the putty.

In my experience, epoxy putties don't stick well during application, so that might create the impression that it won't work. But once cured they are attached solidly.

As stated above, it's best used on bare plastic, and generally recommended to rough up the surface prior to application to key it for adhesion, as the putty doesn´t contain any solvents enabling it to chemically "bite" into the surface on its own.

For optimal adhesion you have 30-45 minutes to apply the putty once mixed, depending on the room temperature.

Less is more, as the saying goes: It's better to apply conservatively and add more later on if required.

One of the many great advantages of Milliput is the ability to accurately sculpt it into shape using moistened tools. Once the putty starts setting, you can gently(!) fine adjust the shape within the first hour or two after application.

I like Superfine White Milliput. It can be like Bondo or used for texture. 
I made the Zimmerit texture on the Tiger II tank by rolling it into thin sheets on a porcelain tile with a Teflon rod for a rolling pin. I used talcum powder to prevent from sticking to either. I scratched up the surface of the plastic with the back edge of a number 11 blade.

The white Milliput is the only way to go with that particular brand IMO.  The green "standard" variety is on the coarse side, and takes a lot more work to get smooth, and even then doesn't approach the smoothness of the white variety.  That, plus I prefer to have everything (plastic and putty) in one color whenever possible, as I try to use a minimum of primer while bodywork is in process.

You should be aware that it has a shelf-life of about 2-3 years. Beyond that it becomes less reactive and takes significantly longer to fully cure. Sometimes it helps a little to cut away the outer layer and only use the “core” of the older putty sticks.

Milliput is an incredibly good filler, just be careful not to do what I did. After a very late night of construction, I fell asleep with Milliput under my nails, the pain in the nail bed from the hardened sharp putty chemically bonded to the nail tormented me for a week.
