Styrene solvent glue and Tamiya putty

[BK9300]

Never worked with Tamiya putty other than to fill small holes/gaps.  I need to cover part of an area of a hood to maintain an curved profile and then add a strip of styrene down the center of the hood.  The strip will cover an area made up of bare styrene and some Tamiya putty.  I've always preferred using solvent glue to bond styrene to styrene - does solvent glue bond with Tamiya putty or do I need to use a different glue (CA, epoxy, ?) to attach this strip?  Thanks for any suggestions!

Solvent glues work by "melting" the styrene, so they wouldn't work on the fillers. I have used super glue and reinforce where I can with 2 part epoxy for strength

Martin Kovac, A.K.A. Uncle Night Shift, mixes solvent glue and Tamiya putty all the time for adding cast steel texture to model tanks. I see no reason that it couldn’t be sanded smooth. It’s Tamiya putty thinned down.

If you need to build up a fairly thick layer, I would recommend a two part filler like Fine White Milliput (my preference) or Tamiya epoxy putty. It sands easily and won’t shrink like a solvent based putty. Then I would use solvent cement to tack the styrene strip to the bare styrene sections of the hood. Once it is perfectly aligned use CA to attach the remainder to the puttied area.

Thanks for this link - might not suit me immediate purpose, but is very interesting!

Thanks for this, Greg - no layers to build up, just an area, part styrene and part filler, that needs a strip of 1mm styrene added on top.  Likely need two glues, like you suggest.

I just mixed Tamiya putty with Tamiya Extra Thin cement and brushed it on the cut lines of a Revell ‘26 Ford Tudor Sedan that’s getting chopped up. Not sure I would have thought of this application without your thread.

What's the working time with this? Does it set up quickly or do you have time to shape or contour with it.

I think it would vary, depending on how much liquid cement. I think it will be safe to sand tomorrow night, but I still need to add filler pieces at both bottom corners. All of the glue joints are also Tamiya Extra Thin liquid cement.
