Coating foamies
Hi guys

To those of you who fly foamies (more the expensive edf jet foamies) is there any type of sealer which you can buy to spray on the foam to give it a bit more strength and save landing rash? I know you can glass a foamie by using silk etc but it seems like a huge hassle and I was wondering if you can use a clear coat paint varnish type product. Obviously it can't be something that will eat foam

I have a fly fly 90mm bae hawk which is a big bird but I would love to take away a little bit of the foam look.

cheers

I know some people use Tamiya TS spray can paints to coat their planes and flying boats. Tamiya TS paints make the surface stronger and water proof. Make sure you use only the Tamiya TS paints and not the Tamiya PS paints. The Tamiya PS paints will eat the foam, the TS paints will not. You can also use some stick on RC plane monocoat to make the bottom more durable. Not sure why the picture is small here, but you can look at the larger size in my gallery.

Take Care,
Cheers, Patrick

I read on RCgroups that you can get a floor sealant that contains acrylic. You can spray it on or paint it on to a foamy. It's sort of like an acrylic clear coat. I can't remember the name of the stuff. I found it burried deep in a foam painting/finishing thread and can't find it now.Stupidity can be cured. Ignorance is for life!

I took 5 min epoxy and those micro balls and coated a stryker with it. The thing was bullit proof.

many many times works great and then you can use reg paint as well

on the spots for belly landing I also add 1/4oz fiberglass cloth

Its a little more work to get it right but I always used a low-heat monocote for covering foamy's. Its tricky on the compound curves but forms a VERY tough exo-skeleton and usually only adds an oz. of weight. Just another option.

talegunner,

Sure, polyester resin will but epoxy resin won't. I've used the Z-poxy finishing resin on my Miss Hydrofoam with GREAT success.

I'm just finishing up my second Steve Shumate Polaris. The first was bluecore and has packing tape on the belly to toughen it up. it works but needs to be replaced every so often. I'm thinking of glassing it with the zpoxy. I can't use the minwax because it's waterbased and the Polaris is a water/grass/snow aircraft.

I may have to look in to the minwax glassing on my land based belly floppers though. thanks for the idea.

doug, one of the biggest advantages of foamy technology is the lack of a need to monokote it . if i wanted to monokote, id get back into bigger slimers

yes the epoxy will work and will also be stronger and heavier as well

I have used it as well. now that I look back at the OP he was looking for the minwax stuff but yes epoxy will work too.

Yeah, I agree, it's heavier. The OP was definitely looking for the minwax polycrylic. I'm going to be trying that out in the future.

Thanks for the info!

Whats up fellas!

What florescent paints are you guys using on your depron?

I painted my CR-1 (6mm depron) with Neon Pactra paint. Its was the only one that I had that didn't eat the foam. After I painted it, I have noticed that the foam is now really dry and brittle.

On the next kit I build I wan't to coat it with some clear to stiffen and protect the paint. Glad I came across this post.

Thanks boys!

I haven't painted my depron planes too much. My latest Polaris is colored with fat sharpies. It came out pretty good, I'll post pictures when I finally finish it later tonight.

I did use some black Krylon H2O paint on the underside of my hydrofoam and I used an airbrush and red latex paint thinned with windshield washer fluid for the top side. I don't really like any of the other H20 paints as they aren't really vibrant enough.
