58 Impala Posted August 30, 2023 Share Posted August 30, 2023 (edited) I have read several post about people using micro balloons with CA, 5 min. epoxy and other mediums as fillers on their models I've searched the internet and haven't found a good source. Anyone have any sources or suggestions? Thanks. Edited August 30, 2023 by 58 Impala Quote Link to comment Share on other sites More sharing options...
Dave Van Posted August 30, 2023 Share Posted August 30, 2023 I used them 30 years ago. I may be dreaming.....but it seems there was a health rick breathing them. Maybe they are not made any longer. At any rate baby powder works almost the same......with a slight weight dis-advantage only. 1 Quote Link to comment Share on other sites More sharing options...
Straightliner59 Posted August 30, 2023 Share Posted August 30, 2023 They're all over Ebay. AK Interactive even markets them as snow. https://www.ebay.com/sch/i.html?_from=R40&_trksid=p4432023.m570.l1311&_nkw=microballoons&_sacat=0 1 Quote Link to comment Share on other sites More sharing options...
Muncie Posted August 30, 2023 Share Posted August 30, 2023 I found them at a plastics supply store when I was looking for something else. Tap Plastics - a local store that is part of a west coast chain. There may be similar stores in your area. 1 1 Quote Link to comment Share on other sites More sharing options...
stitchdup Posted August 30, 2023 Share Posted August 30, 2023 I just use the filings and sanding dust from my bench. it works just the same as micro balloons and we already have it on our benches and its almost free. you can use pretty much any powdered stuff though, within reason. most of the time i have some filler and plastic dust saved up for using as its handy for holes. theres also finger nail filler but it works best with its own catalyst and it stinks bad, and its pretty tough to file down, 1 1 Quote Link to comment Share on other sites More sharing options...
Ace-Garageguy Posted September 1, 2023 Share Posted September 1, 2023 (edited) Micro and baby powder don't work the same. BP is talc, which is the primary filler in most "bondo" products, and which use POLYESTER resin as a binder. Microballoon used as a filler with an EPOXY binder will do things NO OTHER FILLER IS CAPABLE OF. Use a quality epoxy like West 105 / 205. The 5-minute stuff will just make a rubbery mess. This is where I get mine: a one-pound bag of white micro for $11 should last most modelers forever. https://www.aircraftspruce.com/catalog/cmpages/bubbles.php And yes. DO NOT BREATHE THE STUFF IN.

I would think a pound would last several modelers a lifetime! I still have some in one of those "butter tubs" I bought back in the '80s. I don't think that thing weighed more than a few grams, then. I don't do a lot of serious bodywork, either, though. Quote Link to comment Share on other sites More sharing options...
Camaro lover Posted September 2, 2023 Share Posted September 2, 2023 (edited) When I worked on boats I found micro balloons at a marine supplier. They were usually near the resins and epoxy dept. ETA amazon has them too Edited September 2, 2023 by Camaro lover Quote Link to comment Share on other sites More sharing options...
Mark Posted September 3, 2023 Share Posted September 3, 2023 Hobby shops specializing in radio control should also have micro balloons, should you have any locally and want them ASAP. Quote Link to comment Share on other sites More sharing options...
