I was just wondering. I'm priming and just starting to fill the pin holes, cracks etc, on my Bell 222. I know this is the plane forum, I'm a plane guy too, but this should apply to any fiberglass fuse Now I know what all of you mean by pin holes [X(] cripes sake. Anyway, I'm using the basic red modlers putty to fill everything in b4 I sand & prime again. I was thinking looking at this little tube, which I probably paid $6 for, and a can of bondo (a lot more for the money) I have in the basement which I probably paid around the same or a little more for. My question is: Does anyone use bondo? Would it be to heavy? Would it not stick? I've never used bondo yet. I have it because someone shot a bullet through my wifes door the other week (we were in bed sleeping, I did wake up, it was 3 shots, one hit my wifes car, gang bangers, I'm sure), and I'm waiting for the weather to warm up a bit b4 I fill it in. Back to the subject, sorry. So far I haven't read of anyone using it, so I'm guessing its not a good idea. Anyway, any advice, comments etc would be appreciated. I forgot to mention that for primer, I'm using flexible bumper primer, actual name Wurth saBesto Flexi-Prime. I'm going to use automotive paint.
Thanks!

Actually, Bondo works pretty well for fiberglass parts, but use the lightweight variety and weight shouldn't be a problem. The can I have is marked "Bondo Ultimate Premium Lightweight Body Filler." It's in a light blue can. Walmart, and most auto parts stores (like Auto Zone) carry it. A can will last a long time, and it's not that expensive.

Thanks very much for the reply! I guess it doesn't hurt to ask I thought it might have been a stupid question. But like my dad used to say, there's no stupid questions

Once primed, the bondo isn't the best to stick to the primer. The Spot-n-glaze you're using is the best for the pin holes. The auto paint supply stores have the larger tubes of the primer putty for a better price.

That's true. I didn't read carefully enough and see that primer had already been applied. Bondo is good for bare fiberglass, but the spot glazing material is best once priming has begun. The other alternative is to sand the primer back down to bare material, if necessary.

OK. Thanks very much for the help! Thats all good to know
