ctruss53 Posted June 27 Share Posted June 27 Yes. It actually works very well. But it is very stinky. So be prepared for that if you use it in your home. Quote Link to comment Share on other sites More sharing options...
redscampi Posted June 27 Share Posted June 27 I would guess so. It certainly sticks to everything else. Although it cures pretty hard and might be difficult to sand without damaging the styrene. Quote Link to comment Share on other sites More sharing options...
ctruss53 Posted June 27 Share Posted June 27 (edited) Here, I actually just started a fillers discussion yesterday. I came to the conclusion that a CA with some filler powder in it is worth a shot. Edited June 27 by ctruss53 Quote Link to comment Share on other sites More sharing options...

I sure as H. wouldn't put this much effort into something that didn't work. Edited June 27 by Ace-Garageguy 2 Quote Link to comment Share on other sites More sharing options...
peteski Posted June 27 Share Posted June 27 (edited) As I understand, Bondo is a polyester resin based body filler. It will adhere to polystyrene well. As for the small, I actually like that odor (in small and low-concentration quantities). Edited June 27 by peteski Quote Link to comment Share on other sites More sharing options...
Shark Posted June 28 Share Posted June 28 A benefit to 2 part (catalyzed) fillers is they don't shrink over time like a single stage 1 Quote Link to comment Share on other sites More sharing options...
Deathgoblin Posted June 28 Share Posted June 28 I must recommend when working with the Bondo spot putty: for the love of all that's holy, wear a mask! I was working with this stuff and started developing a really BAD cough. I keep an inhaler, but that wasn't helping. It only went away when I stopped using it. It says on the packaging that it can cause silicosis. It works great, but wear a mask. Quote Link to comment Share on other sites More sharing options...

I believe Bondo contains silica as a thickener, so the sanding dust will also contain silica. Quote Link to comment Share on other sites More sharing options...

Not to be too pedantic, but I strongly recommend reading the SDS for any product prior to speculating on the internet, where everything is rebleated infinitely, whether it's factual or not. The SDS (SAFETY DATA SHEETS) for just about everything even remotely hazardous are readily available online. The specific hazards, types of testing done to identify them, etc. etc. are fully examined here. RE: Bondo Professional (2-part) https://multimedia.3m.com/mws/mediawebserver?mwsId=SSSSSuUn_zu8l00xM8tGMYtSPv70k17zHvu9lxtD7SSSSSS-- EDIT: I've worked with catalyzed polyester resins, fillers, and epoxies (as well as all manner of paint products) for well over 5 decades, using reasonable PPE, good ventilation, and common sense, and have suffered zero ill effects. Read the SDS info, read the instructions (TDS: technical data sheets), pay attention, use common sense, be careful.

Don't sand the part in there, just let it gas out in there. Quote Link to comment Share on other sites More sharing options...
