Gap filler

[greymack]

Anyone ever use super glue and baking soda to fill gaps or do any kind of body work?

I've used 30 minute epoxy and micro-balloons. Some use super glue and micro-balloons. Micro-balloons can be found in hobby shops that have some R-C inventory. The baby-powder & super glue work too and I've heard about it's use from several sources.

Gel type CA with accelerator..sand quick and it works...

Somebody once posted here that hitting CA with baking soda is the same as hitting CA with an accelerator.

Why not just use gap filling CA?

Oops! Maybe it was baking powder. Sorry. There's a difference in baking powder and baking soda, but I don't know what it is.

I would have thought superglue dried too fast to be able to mix it with baby powder or anything, but I guess not. Or do you use some kind of retarder in the superglue?

I don't recommend or at least advise great caution if you try super glue and micro-balloons. Obviously, not all micro-balloons are alike! I also build canoes and kayaks as a hobby and always have boat building supplies on hand including some brownish colored "phenolic micro-balloons" from System Three (a well known producer of epoxies and other boat materials). The INSTANT that the super glue and micr-balloons came into contact enough heat was generated to melt the disposal plastic cup that they were mixed in. It also released some very nasty smelling and probably toxic fumes. Fortunately, I didn't catch that full in the face but I won't be repeating that experiment!

The System Three microballoons were intended to be mixed with epoxy and they work great like that. I've heard of other people using super glue and micr-balloons successfully so there must be different types but I think I'll just avoid the whole thing!

If you look carefully...find the "slow" CA...gives 30 seconds to work with

Hi guys yeah thanks for all the replies on my topic.I mostly use 2 part automotive body putting work fine and I'll have to experiment with the super glue mixtures sometime.

From my experience it's not the same. The resin kit I tried the superglue/baby powder mix on had a spot on the backside of the front fender that was extremely thin. I knew it wouldn't stand up to sanding, so I used one of my picks to open it up all the way into a small hole. Now, using gap fliing superglue by itself might have worked, but it would have taken a lot of it to do so if it did indeed work. By backing the hole with masking tape, & mixing the glue/powder combo into a paste, I was able to fill in the entire area quickly & then go over that with just enough superglue to fix any low spots. It dried rock hard, & sanded out perfectly. Accelerator with superglue wouldn't have made the same thick paste required to fill in that void, & putty would have popped ot of it.

I've used Goldberg Superjet with Bob Smith Accelerator to do this for perhaps 25yrs now. works just fine. SuperJet is a medium viscosity CA, Bob Smith Accelerator works without bothering the neighboring styrene one iota.
