Next Spring Project...

I'm still adding weight to the bow to offset the 2 8D batteries under the rear seat! Between this project and the extra 160# of water, I may be back in the world of full displacement trawlers.

On the otheer hand, if those are little glass balls, maybe you are adding floatation :wink:

I am sure the factory guys use it ...to thicken the resin for spraying...

It's fun to play in... you stick your hand into the bag...and it feels like air...sticks to your hand like dust.. fun to throw into the air and watch it float...

It would make a good insulator when mixed with paint...

You could also make a MONDO omelet with it.... Nice ....light and fluffy... It really is mixed into catsup to thicken it....will pass thru your digestive system easily..

It is also used in high quality light weight BONDO...regular BONDO uses wood flower as it's filler....

It is sold under the name of CAB-O-Sil

Cabosil Fumed Silica 250g [Cabosil Fumed Silica] £2.20 - £5.61
Price does not include VAT @ 17.5%



CABOSIL Fumed Silica, for use with polyester resins and used primarily to thicken a resin to prevent drainage on verticals and overheads. Best allowed to soak in resin for a number of hours or overnight before use since it can be difficult to disperse in all resin types. Simply add to taste but not above 15% by weight. Excessive useage will result in a weaker laminate and possibly that the fibre glass matting may not wet completely.

Due to the cube of this product most people require small amounts. Each item you buy is for 250g lot of Fumed Silica. Should you require a full 10kg bag, please add 40 units to your cart. You will be sent a complete full 10kg bag and be charged accordingly
 
Roger that merv! :shock: Tossing it into the air is not a good idea. When I used to use this in fiberglass repair years ago, we wore respirators before it was fully mixed into the resin. From what I was told then, the spheres are so small that they will enter the tiny sacs (alveoli) in your lungs and stay there. This may be different stuff but I wear a respirator from start to finish with this project.

Roger,
Amen to that.

Coming from a nation of coal miners I am horribly aware of the effects of Silicosis. Seems to me that inhaling glass silica balls is very much the same issue. You might be wise to spray a sealing layer of something on top instead of sanding which would just let more of the little buggers loose.

The whole problem of microscopic particles gets even more scarey if you go to a lecture on what happens to plastics left to rot in the ocean. They eventually degrade into microspheres which are small enough to be ingested by the lower forms of microorganisms which are the food for larger beasties such as shrimp, crabs, fish, whales, seals and humans. If you think what the plastics are made of it is not too palatable or healthy.

Not that that fact is going to stop me eating my share. I firmly believe that wine offsets the effects.

Ciao,

M

I'll go w/ rum & coke. Higher alcohol by volume should work even better! :lol:
 
Well, this project is done for the moment. A pile of bark has replaced the boat in the driveway :(

I have applied 4 coats, sprayed on. This used about 1.5 gallons of product. 1 gallon paint, additive and water to thin for spraying. Cost for this application, $37.00. The surface has a definate gritty feel to it. It is not objectionable but could be top coated to smooth it out. I used Behr interior satin paint from Home Depot.

The dome lights will be re-positioned on either side of the port hole and should provide better reading light. We'll try to get out to the state park soon for a test night on the boat. I'll report back with the results.

So - Roger have you had the boat out yet to see how this insulation performs?
