I have never used the squadron puttys before, I have done scratch building though only i use a different type of filler. What is the difference in the green and white putty? or is it just the color?

Daniel, Squadron Green is good for building up details, the white putty is a bit finer for finish sanding, finer grain. Hope this helps, Paul

Let me add, don't ever think you can fill a gap with putty. If you can, fit/fill the gap with styrene or a filler rod, then use the putty to finish the fill in.
Why? Because all putty with shrink. Most guys learn this the hard way when they do a job. Another lesson to learn is that you will want to do multiple layers of putty in some cases.
I've not used white putty in a while, because I learned a few things about green that will make it more 'flat'. If you take a brown paper bag and use that as the final sanding, it will push in any groves you get during sanding.
Oh heck, this isn't about all this crap so I'll just stop now because there are 1001 ways to do it and I'm sure we are all different. LOL

Good advice, Matt, but this is the first I heard about the "brown paper sack" method for finishing (my brown paper sack is my "redneck coozie" ). How about telling us more??

A little trick I learned from 2 different sources. One in auto body and the other worked in clay!
Seems the fibers in the paper still allow a sanding action, but they don't grove out the material like standard sanding paper will. And after working the area for a brief period of time, it simply fills over the voids caused by the sanding paper used previous.
Now, don't think you can avoid sand paper, you still need to use it, but the brown paper bag is the final step. I just use what we get from the supermarket, one bag will last a long time. I just cut it up into small squares the size I need and use. As the paper wears, it will get a shine to it. Just like sandpaper, you can tell when its all done!

Speaking of automotive materials - you can get the red glazing putty, and it works the same as squadron, comes in a tube about 300% larger than the squadron, for the same price. In regards to hobby putty - I think the tamiya stuff is tops. Hard to get lately though...

Most guys use the Squadron putty because its in the shop they are at.... Also, most don't like to try other stuff because of the ability to screw it up! LOL

Yeah I know what you mean. I have used just regular bondo for the past few years and the smallest can of that stuff last forever. I'll probly stick with it because i know to use it.

I have seen wood filler used for models because it doesn't shrink so bad.

That stuff is foul smelling too, follow the directions and use it in a well ventilated area. I try to do my filling outside and wait about a day until the fumes die down on the model.

Just for information... Any putty that is ready to spread, out of a tube, will shrink, and keep shrinking. These puttys cure by the solvents evaporating, and the filler solidifies. This process does not stop, as the solvents can take years to fully dissapate, hence the shrinkage that appears after a project is done.
The putties that require a hardener mixed into them, cure by chemical reaction, and therefore there is no solvent to evaporate. That means that they don't shrink! They also usually cure quicker than the one part putties, and can be applied a little thicker. There are several brands available, I use "Icing" by USG.

Your point is well taken, and in fact, I've had more problems with shrinkage froom Squadron putty than any of the other solvent based putties I've used. I'm all for a putty that doesn't shrink at all, though. How do you mix USC Icing in small enough quantities for a typical putty job? Instructions I've found say a 50:1 ratio of cream to hardener is required. That's tough to get accurate, especially when I'm only needing about a 1/8" diameber ball's worth (or less) of putty to fill in a crack or a seam. Thanks, - Arved

Arved, I have had good luck with several of the two-part epoxy putty compounds (brands like Milliput, Andrea Sculpt and Magic Sculp, with the Milliput Superfine white being one of my favorites). They all seem to work well with plastics.

Thanks. I'll give Milliput a try. I think I should be able to find that one nearby.

Hi ICGHogger, Has anyone tried the LePage Blue/White epoxy as a putty? No, where can you find it, Ron? All the big box stores in Canada, anyway... Lowes, Home Depot, Walmart and Staples, etc... It has to be worked quickly but it would fill large holes. LEPAGEĀ® REPAIR EXPRESSTM EPOXY PUTTYJB Weld makes a similar product...
