Body Filler

[JMD904]

I have a AMT re-issue of the Double Dragster Kit. It had a Fiat Cuope and a FED. Anyways, I'm building the FED and I noticed there's a horrible sink mark on the back side of the body! In fact, it has a tiny tiny pinhole on the outer wall and is transparent. How can I fill this back in? I need something easy to work with and easily sanded. What can be used and what grits of sandpaper do I need?

Without getting into another thread on all the possible puttys to use, for soemthing like this, a little superglue with a lil baby powder added to help fill it in. I use it constantly.

Same thing different powder. I use Baking Powder instead of baby powder. Same result. sets up almost instantly and can be sanded in a few minutes.

They are some great tips, I don't have the cash to get any body filler so I was just using my model glue alone to fill holes. Does the powder make it dry faster because the glue alone seems to take a while to dry?

Baby Powder (talcum powder) is what some modelers use to set uo Super Glue (CA glue). The stuff works fine for simple filling of sink marks, etc.

I think super glue by itself would just sit there. Not sure about the science, but it seems to need something to bond to before it does anything.......the powder sets it up immediatley. baby powder or baking powder is something that just about all of us has in the house.

For pin holes, depending on size, I drill out & fill with evergreen styrene rod, or sprue.

I even make filler with liquid cement, & kit shavings.

The problem with using Superglue as a filler, is it will be harder than the surrounding

plastic. Extreme care will need to be taken so as not to create a raised spot surrounded by

low spots!!

I use the medium viscosity superglue as a filler all the time. But I don't put anything in it. However, I do use an instant setter called Zip Kicker. This makes the superglue set up almost instantaneously. And Dan is right about superglue becoming harder than the styrene...it will...but not for about an hour or so. Which means that you should do your sanding right away so that it doesn't have time to become harder then the surrounding plastic. What I do is...fill with Zap-A-Gap superglue in the green bottles...hit it with a spray of Zip Kicker...blow on it to evaporate the Zip Kicker...then wait 20 seconds or so...then start the sanding. It's the fastest way I've ever seen to fill things like you're asking about. Airplane modelers have been filling seams with this method for 20 years or more. I know because i was filling the seams on my aircraft models with this method back in the early 90's after some of my fellow modelers showed me the method!
