Help getting rid of seams
Posted by zackesch on Friday, November 7, 2008 11:15 AM

First off, this is my first attempt at airbrushing with enamel, comming from tamiya acrylic and i must say, enamel sprays much better and is more forgiving.

 

My question is, how do you get rid of seam lines? I tried sanding it down to a polish grit, but as the attached picture shows, i had no luck. On a hidden part on the engine, i tried using squadron green puddy, straight from the tube, but the putty is still visiable when painted. Any tips on what i can do?

Thanks!

You can't post pics as attachments or directly from your computer. They have to be hosted online first.

First of all, you should apply enough glue so that you get a very small bead of melted plastic coming up out of the seams. It sounds sloppy, but it is the best way to fill in seams. You then simply sand them away.

What kind of glue are you using? And when you use Squadron putty, you should thin it into a thin paste with Testor's Liquid Cement, which will help it fill in the seams. It will work every time. Sometimes you may have to reapply it if you thin it too much, but you'll get the hang of how thin/thick to make it after a little while.

I am using model master liquid cement. I will also try thinning the liquid putty.

You might want to try Tenax R7, Plastruct Plastic Weld, or even Testor's cement. I don;t know about that Model master cement, but I can telll you that I wasnt very impressed with Model MAster Bare Metal Foil...

Also- and the masters will tell you this, won't they, DOOG?

Seam defeat is 90% before they join, and 5% after. The rest is luck. Kind of like sex.

Don't base your victory on cleanup, base it on clean building, again like um...

Really.

There is a trend in publications to talk about fill/sand/prime paint which is all well and good, but...

Put it together carefully and correctly, and in almost all cases the rest is not necessary.

I think it looks pretty obvious that not enough sanding was done to begin with.

Not directly related to your post but, cars are a bit different from other models.

You want to be careful and look at photos of the real car. Real cars have seams, and as modelers we have a tendancy to want to remove seams. It is worth taking the time to see if the seam actually has to go.
