Filling Seams

[Bill L.]

Gunze (Markers of 'Mr Surface') sell that very compound (Tamyia Extra thin and sprue) as 'Mr Putty'. It is a variant on Mr Surface....  I found it last year and have been using it. Works well.

I like to use very small gage rod stock from Evergreen plastic. Just cut to length, Bend if needed. It is pretty flexible. Add glue to soften, and work into the seam.  I then allow to dry overnight.

It is white, so the color is no issue. It can also makes a good weld seam if you work the soft plastic with an x-acto blade.

I used a really light grey sprue...

I have heard of doing this but have never done it myself. The only caveat I would add would be to use light colored sprue for the addition to the Tamiya Extra Thin. a dark colored paste may show up as a panel line under light colored paint.

I know you guys were talking about this the other night at Applebees, and I meant to mention that I tried something new recently. Well, new to me anyway...

I dissolved sole leftover sprue in the remainders of a bottle of Tamiya Extra-Thin...The styrene melts down to a runny paste consistency and I applied a small bead along a couple of seams on the P-51D build...waited 24 hours for it to solidify and a little sanding and the seams were gone...

My only complaint is that it really needs to sit overnight to solidify...

IBRA: The type of glue you need to buy is Plastic-Zap Medium.  Apply to the seam (I use a toothpick), let it dry for 45 min to 1 hour, and sand with a flexifile and it should come out extremely smooth with the seam gone.  If it doesn't work the first time, just do it again.  I think you'll like it better than putty.
