Ok so ive just put together the two halfs of the 88mm metal barrel together, but you can clearly notice the 2 joins running down the lenth of the barrel
What is the best filler, to use or what is the best thing to use to get rid of these seams
regards

You can use Tamiya putty thinned with Tamiya thinner,just paint it down the line and sand it smooth.Some might use a Mr Surfacer product and sanding.Any putty would work.

Vallejo modelling putty is not bad either- it dries very quickly though and can get messy. If the join seam is small I would use Mr. Surfacer- if you have it.

For metal parts I prefer to use a commercial product called Bondo. It dries hard as nails, dries fast, and doesn't shrink. A tube of Bondo will last you a life time.

Hi Joshua,

I agree with Joel. i use 3M bondo spot putty in the red & black tube. that stuff is great.

The 1st time I read your post I missed the part that you have two halves of a metal barrel ,why would a metal barrel come in 2 pieces? I thought the purpose of the turned metal barrel was not having to deal with the seam? I'm just saying

Thanks for the Tips guys, and sorry for the late reply, my computers been down for last couple of days

The barrel for my tiger tank came in 2 partsvtoo

I used milliput which was quite malleable to work with and set quite nicely. Came with 2 sticks. You cut a piece from each and mix them together. They react and set hard after a couple of hours.

I too use Bondo Spot Putty in the red and black tube. Best modeling putty I've ever used, and it's dirt cheap. It works on all materials and sands perfectly.

If I was going to use putty on a barrel I'd use Magic-Sculpt- with a little water it will sit into very small gaps perfectly and it sands nicely aswell.

It's hard to get modeling materials here in Nicaragua. I think I saw some Bondo last time I was in a hardware store. Can acetone be used to dilute Bondo?

Hey,

In my opinion after trying a lot of different types of putty fillers, they ALL hold none in comparison to polystyrene.

Just scrap off flakes from the sprues with your modeling knife and melt them with liquid cement into seams, gaps, etc. and wait for it to dry. Then sand it.

That's a good question Gendrok. I too use Bondo and would be interested to know what can be used to dilute it.
