My Home Depot has sold Bondo GP resin for a long time – yellowish label. Its always said it doesn’t shrink which is a lie depending on what they mean.
IF they mean during curing its a lie though our uses are not “normal”. For fiberglass layup, it probably shrinks so little that no one would ever notice (how do you measure the width of 2 gnats eyebrows?). For casting pours it does indeed shrink. In pouring a 10oz HHG in a martini glass the resin easily shrinks about 2+mm (around 1/10 inch).
This stuff is kind of honey color and as far as I know they’ve been selling it for a long time. I think IIRC they did switch a while back but it was a year or two ago.
I dislike the Elmer’s resin that Lowes sells. First off its blue – at least the gallon or two I bought before I realized the stuff HD was selling is much better. Its thinner which in a way is good (flows better) BUT man does this stuff wreak. The odor will practically knock you off your feet!
Have to take a trip to the local HD after Christmas to make sure they still have the same stuff. Even still I really need to find a much more inexpensive source (local). I’m starting to use enough of it now the cost is starting to hurt.
look around for a short run manufacture of fiberglass, I found one and get it for 75 to 80 for 5 gal, the one i found makes fenders, doors for off road, and makes tanks. Really helps on cost. Shrinkage is good helps get them out of mold.
The best all time deal i found on resin before was a boat retailer i forget the name, who had a clearance on resin from their warehouse but would ship to the local retailer.
25.00 for a 5 gal! Alot better than hd – 43 a gal. at least they give you 2 bottles of catalyst.
Finding cheaper resin is usually just a matter of googling local sources, or nearly local. I think Doc Stevo gets his resin from a local manufacturer of hot tubs. Ben gets his for low cost by taking his buckets to a resin seller who normally sells it by the drum.
A very big scale orgonite effort is cheaper if you buy a 55 gal drum but you’d need to use it up before it starts to gel in the drum, of course.
A drum does all the death towers, etc., in a pretty big city.
Before long, someone (probably a gov’t in Africa) will produce orgonite on a very big scale and when this is common I think people will read our old reports about the price of fiberglas resin at Home Depot with nostalgia
Capt Azti and I conceived a plan to drop orgonite along ley lines in the seas from a twin engine turboprop, using a special, metered dispenser of towerbusters under the wing.
He’ll pilot it but maybe he’ll let me copilot and land it, sometimes [Image Can Not Be Found] He told me that he once barrel-rolled a Boeing 707 cargo plane and I believe it, especially after watching him fly my little plane–what chutzpah! When he came in for a landing he banked sharply around a tree at the end of the runway, into the final approach. He hadn’t flown in years but he got into the plane like he was putting on a pair of pants and just took off.
$43/gal at what HD? Europe? The local HD is selling it for $35.99/gal – got a gallon of it 2-3 weeks ago for this price. Add the 7% sales tax and a gallon costs me $38.51.
I do have to call around. There’s gotta be someone who uses this stuff in bulk around here. 10 gallons ought to hold me for a good 6 months but I’m not doing this at HD prices.
And yeah, what Don says. Resin manufacturers date code their product. They will only guarantee it for structural applications for a period of 6 months from the date of manufacture. It’ll keep much longer than this if you keep the drum cool and limit temperature excursions but I’d figure a year might be pushing it. What inevitably happens with long-term storage is that it starts to harden by itself at the bottom of the can and can become thicker in the can also (the wrong direction for it to head).
Epoxy doesn’t seem to suffer from these ills – had an epoxy manufacturer tell me that even though they only guarantee their product for a year, they’ve had test batches that even after 5 years still performed equally as well. No I wasn’t using this stuff for orgonite – way too expensive.
