Putty Suggestion...part deux

I know there is already a recent post, but I have a bonus question regarding putty types.

I will be soon working on a He 111 (Roden kit) that will have a gap between the two fusalge halves to ensure the canopy sits properly.

Knowing this in advance, I have read that some putties shrink quite a lot and the final dried texture may not dry hard enough for scribing later. Also some are prone to crack upon further handeling once they are dry.

I was thinging of using the superglue mixed with talcum powder, but if further sanding is needed, i have read that it can be super, super hard to do (due to the texture drying).

So, what are the best putties that shrink little, dry hard enough for scribing later and are easy to use.

Thanks,

T

Oh…and can be sanded farily easily…

Two part putties generally do not shrink, as they do not “dry”, they harden with a catalytic reaction. Bondo is a polyester putty (the two part stuff. I believe there is also a solvent version, which shrinks like the others). Most tube epoxy glues are thick enough to use as a putty also, and I have used them a number of times to fill seams. I have also used gel CA to fill seams. Since I generally use needle file to clean putty on seams, the hardness of it is not an issue for me.
