2walla, that is a good idea. If this is as easy as they say it is, this product would be a great alternative to glassing. I just finished my first warbird and I hate to say it but I monokoted it for fear of glassing. If this product is good I will not hesitate to use it for my next project. Tfarmer keep it up with your experiments. It is helping everybody out.

ORIGINAL: scale only 4 me



your mean .48 & .26 ounces, not grams right? or is the 48 & 26 grams??
[/quote]

The scale was set to troy oz...WTH?

Any way if you do the conversion from Troy Oz to grams its.

.26 toz or 8.08 grams dry weight with nothing on the sheet
.48 toz or 14.92 grams with 2 coats

Sorry about this i should have looked at the setting on that scale.

Thanks for catching that Scale only 4 me

Can I suggest that you make a couple of stress risers in your test pieces- put in a couple of glue joints both parrellel and perpindicular to the grain so that you can do some flexure testing to see if it cracks over the joints. I used to paint my quickie 500 racers and tried several things to seal them up- the best thing ended up being mod podge thinned out a little bit with water. It held up great- you should try a couple test pieces with it..
This is a good idea. I was wondering what this stuff did if you bent the sheeting until it broke. Let glue some sheeting together. The photo in this post is of the 1/8 sheeting that has had the product on it for 20 hours
check this out. The wood didnt even crack.

We will see what it does in a few days.

There was never a claim that it strengthen, its a cover for painting. If you needed to strengthen your wood you would have to glass it. I bet this stuff would work great over glass, I am going to test panel over glass.

You got it, I was trying to do the math.

So your test sheet is 54 sq. in. and you added 7 grams weight, that would calc to .13 grams/sq. in or 18.6/sq. ft. That less than an ounce per square foot,, not bad I guess
If I had a more accrtate scale I'd do a test sheet with .58 glass cloth/epoxy to compair the two

carry on,,,

Its flexibility might not be an indicator of its tensile strength. Spanwise the tensile strength might stiffen the wing. Think about how easy it is to twist a wing on a free flght model and then how much it stiffens when the dope and tissue is put on it. Or, think about a rubber band.

Great job. I take it from the videos that there is not much of a smell to this product? It look very interesting. John T.

Its not bad. I know i keep sniffing it. I expected to have some kind of fumes when i thinned it out because i was adding a 3 part that wasnt made for it. It does give off an oder but nothing like say enamel paint.

I agree unless it hardens more in 7 days.

It would be interesting to see what the same size sheet would weight with a coat of glass or an iron-on covering on it.

Thanks for this test!

put the 320 sand paper on this stuff after 24 hours it sands much better. also i think 1 coat of the thin product would be enough to paint over.

Subscribed!  This is a very interesting product, project, and thread.
My wifes TopFlite GS Corsair is almost ready to finish sheeting.  She wants black monokote, but I prefer Solartex or glass.  This product would allow me a good substrate for a great paint job.

This is exactly what I need, an airplane coated with Flubber! If I drive it into the ground it'll bounce back! It would be interesting to know after you paint it how it would hold up in the sun for a couple of hours just as if you had your model in the sun.

It will hold up just fine. The product is made for the indoors and outdoors. Some of those foam figures are I would think are not indoor ornaments. There are placed outside for the public to see rain , sun, snow hot or cold.

I’m shooting primer on one side of the side experiment right now. I will shoot some rattle can paint on the full plank after the primer dries.

Farmer, why would you use primer at all? From what it sounds like, there is no grain to fill.......

becouse a paint job is only as good as the prep under it. primer is formulated to give the
paint something to stick too. don't wanna have to re-paint it every couple of years.

I just wanted to test it both ways. I would use primer in any case, but thats just me.

the small test plank i did on sanded wood with the method called for application with non thinned product and applied with a bursh is now over 48 hours old. Its flexible yet reamly hard if that makes any sense.
