I always like to help where I can, so when I ran across this product, I thought you guys might make use of it....
So you want to make a body for your kart, but too timid to try fiberglass? No problem. You want a light weight body, durable, and scratch resistant? No problem. You want something easy to work with? Again, no problem.....
I was given a sample of this stuff called styrospray. It's pretty nifty! You can brush it, roll it, or spray it. It gets rock hard and is workable (sand,grind,paint... )..... It's a 2 part resin, that hardens only with the moisture in the air. Will not dry up in the can or gun.... :wai:
Now, you're asking, how does this help you? Well, now you can make body panels out of thin eps foam sheets, and coat them into a rigid panel. Foam is cheap, and pretty easy to work with. You can fix mistakes, before you coat it....
Another cool thing about it is, it's smooth finish, even after applying with a brush. I'll post a pic of the sample I have later on. It's brushed on to some wood. It's hard as #€££.... And smooth.....
Yet another cool thing is that is compatible with colored pigment (which they sell ) so you can get it in more than just off white.....
I've glassed over wood paneling to make body panels before and it was messy. I think I might try this next spring.....

wow awesome find, brings lots of ideas to mind about how to shape different things you wanna build, seems simple enough too for anyone to use and if you mess up just put a new coat and try again, very cool

Thanks a million Jim.. I was trying to find that stuff for ... like a month or so...
I say some brush on stuff in a YT-prop-maker video, but that wasn't available in europe..
I can't seem to find a european distributor for styrospray as well (but I only searched for like 5 mins yet ;))

So, at least another option :D

I just watched the how to video, seems like you need to use their primer and hopper gun.

Here is a little info i found on a forum from 2010 of an email a guy got from the company, gonna be a bit more to buy

Pricing for the StyroSpray 1000 is $55.05 per gallon. It is sold in 2 gallon kits, $110.10 for the 2 gallons. We also offer a smaller 2 quart trial kit for $29.00.

The price for the optional StyroPrime foam sealer is $26.97 per gallon it is also available by the quart for $8.25. Coverage for the sealer is 150 square feet per gallon.

StyroSpray 1000 does not contain water or solvent, so your coverage will be much greater than other coatings you are using.

A gallon of water based paint is usually about 40% water. A gallon of house paint which costs $35.00 actually costs $49.00 when you factor in the lost water which evaporates away.

With StyroSpray nothing evaporates away. We do recommend a heavy coverage of 50 to 60 square feet per gallon for outdoor applications.

StyroSpray is nonhazardous and nonflammable for shipping purposes, it contains no VOCs.

To place an order please call us at 800-766-3832 / 713-943-8451, we accept all major credit cards. We are the direct manufacturer of this product and we ship direct to your door via UPS.

Compared to fibreglass, that's not expensive...

The only thing that concerns me is, unlike fibreglass, it's not removable from the base: With fibreglass, you can make a mould, lay the glass &, once it cures, the job will pop out of the mould; not so much with this, it seems...

Most things I've seen unless there is some kinda solvent to it won't adhear to most mold releases, silicone or otherwise based type products.
But defiantly try a sample before the final item.

Cool sounding stuff.

Very true.. but that way you can make a nice permanent plug to mold your negatives from;
and sometimes a single model is all you need, and if it's not a carbody it's still a perfect replacement.

I looked around for a bit more, and such spray on stuff is available here as well,
the bad thing for me, it's not exactly end user friendly so back to the brush on stuff :(

Pics of the sample piece I got.....
I didn't have a lot of time to research, earlier, but I'm pretty sure it can be used in making molds.

cool.. much better than the stuff I saw on YT...,
that was more... gypsum-plaster-esque, not nearly as smooth as that stuff.

:thumbsup:

By your pic, This apears to be a few mm, 1/8" thick?
How long abouts does it take to be "dry"?

No, it's only about .040" thick. That only took like 30 minutes or so till you could touch it. It was rock hard the next day..... That link shows a drying and curing time table, at the bottom, I think.....
