Idea

can the flite test foam sheet models be fuel proofed?


As shown in the vids topic its is possible to fly some of the flite test kits on glow.
Biggest question is if the waterproof foam is already fuel proof or needs additional fuel proofing.
If so what would be best?

Water based Polyurethane is fuel proof and won't attack the foam,it also makes cleaning of oil easy.

As pointless digression WPU .. Ain't Urethane at all !
Merely a high solids Acrylic varnish...an imposter.. product..
That said it fits our needs, despite the misleading advertising/namings.

That's not correct, WPU/WBPU's are most certainly urethane.

They retain the Plyurethane laminating adhesive, but replace the oil-based solvents with water-based solvents

The WBPU smell reminds me of commercial grade acrylic floor wax, may be a derivative product, one of the other or vice versa.

Commercial grade acrylic floor wax typically is one type of WBPU.

We tend to use the name for an entire family of chemicals for a couple specific products. There are many WBPU's other than the Polycrylic product line.

Actually, I should have mentioned but it is my Polycrilic varnish aroma, which oddly enough did smell like acrylic floor wax. I'd almost say that if I knew what acrylic floor wax product to get that was or behaved the same, I could save quite a bit "going generic".

So would any of the Krylon spray paints work?

Not sure about the Krylon, but Future floor wax is the brand that I have heard of using. I forget the app, maybe for foamies, maybe for silkspan. It is the clear stuff though.

Future is the greatest stuff for canopies.

Never tried it as a fuel-proofing solution though.

fuel will not eat up DTFB. in fact, ive flown a few models made from DTFB, one being the ft mini scout with a peewee .020. the foam holds up fine, but it will soak up the exhaust like a sponge ad the paper will come unglued and wont stick to anything. glow flite test planes are fun projects, but by no means long term.
