Hi Foamie Fans :~)
Ever notice how dull the finish is on so many Foamie planes? ,,, and how the decals often peal up so easily..?
Here's a Fast+Easy Tip for coating Foamie Planes; and it's SUPER inexpensive, Light-weight, Won't attack Foam, and is VERY durable to boot.
The product has been around since The 60's (believe it or not), and it's called "Mod Podge". (I got this stuff at Wally-W)
It comes in 'Gloss', or 'Matt' finishes. Just Brush it on; wait till the milky/icky looking stuff dries, and "Bingo", you have a nicely-coated Foamie.
It also offers ALOT of protection for the more delicate Foam that some Mfg's use, like GuanLi models. (easy to 'Ding').
Just avoid getting it down in the control-surface hinges (critical moving parts). If it happens, it's no big deal, because it can be removed.
The stuff is Water-Soluable; Dries Clear+Hard, and it may need to be thinned a little before you brush it on. But other than that, it's a BREEZE to apply to Foamies. The Result is A-M-A-Z-I-N-G (see pix). I know,,, "Shiny" is not intended for Camo, but this pic shows what it can do.
Pix are 'GuanLi A10 Before&Afters', and 'TW AT-6 Before&After'.

I use a 'Fine-Haired' Brush, about 1" wide. I imagine you could also water it down a little more and Spray it with a mini-spraygun if you wanted to.

Thanks, Ramius; and welcome to RCUniverse!!

Trying to find a flat finish, I have found this information about the product:

http://www.plaidonline.com/apmp.asp#ModPodgeBrands

It can be found at Wal-Mart, Michaels and ACE Hardware, among other retailers.

Since it comes in both gloss and MATT, it would seem more appropriate to use matt on warbirds that originally were flat finished. Have you tested the matt finish?

Did you weigh before and after to see how much weight the stuff adds?

Local stores like Wally, would probably carry only what their staffers would suggest I suppose; like Gloss and maybe Matte.
However, as I check with plaidonline-com, it appears to also come in Satin. And there's yet another type of this formula called 'Hard Coat Mod Podge'.

Here's the deal: This stuff does dry to touch fairly fast (few hours); however it will take a few days for it to completely cure to where it no-longer 'feels tacky'. (It's weird stuff).
If you're not using that 'Hard Coat Podge', you'll experience this. I have not seen/used the Hard Coat, so I can't say much about that one.

Plaid put this advice on their site about it:
<p style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 13px/normal Arial; color: rgb(102, 102, 102); ">Hard Coat Mod Podge dries clear with a non-tacky surface. If using Gloss, Matte or Satin Mod Podge apply a clear acrylic sealer to the surface after it has cured.<span class="Apple-style-span" style="color: rgb(0, 0, 0); font-size: 12px; ">

I haven't had that much trouble with it 'feeling 'tacky' for more than a few days. Bear in mind it's already cured,,, it just "feels strange to the touch" (i.e. tacky for awhile)(weird stuff)
But it dries Very clear, and is Very durable (remarkably so, IMHO).

About the Gloss I used: I couldn't find the Matte right away, and I had the Gloss 'in-hand', and I already knew how well this stuff works.
And,,, if I find the Matte later-on, I can apply it directly over the Glossed Camo Warbirds you see. (It's remarkable stuff).
I also knew that using 'Gloss' on these birds was about the best way for me to show everyone some easy-to-see examples. (Matte would not have shown-up very well).

The added weight: I don't have a scale offering the granularity necessary to distinguish the difference 'before/after'; but I'll try to get some figures on that for ya.
It's kinda like weighing the skin you peel-off from a sunburn. Most of the weight is water, which evaporates during it's curing. I'm guessing it's leftover mass might add up to 1/4 oz max.

The absolute BEST advice I can offer everyone is to try it on a 'Test Piece' FIRST, and see if the results are In-Line with your needs.
It does not dry "Glass-Hard-Brittle", but rather stays 'Flexible'.

Hope this helps :~)
