Looking for a good filler for my plastic model kits, been using Deluxe Perfect plastic putty which does everything I want but doesn't keep very long, the Squadron ones seem to harden quickly as well. Any advice.

I use the Vallejo filler, nice to use, does harden in the applicator tube but I tend to apply it with a toothpick so not really a problem.

Been using this stuff 330212
Seems to do the job! Only thing is to remember to wipe the cap & tube threads before finishing! ( otherwise the cap is a real b****r to get off )

I used to use Revell Plasto:



and was quite happy with it, though it really needs a bit of kneading before use, else you’ll first get glue-type stuff from the tube rather than filler for quite a while. By squirting out the gluey stuff first, the putty is much more usable — especially once so much of the glue has gone that the putty is mostly dry when it comes out of the tube.

Since the last local model shop closed, though, I’ve been using car body filler from a tube instead, and that works fine too.

Dip the end of the PPP tube in water before putting the cap on.

I can't get Vallejo filler to stick to anything! Fine for filling a gap between two parts, but no good for sink marks as it falls away when sanding.#

Do your clean the surface of the plastic first and then allow it plenty of time to cure?

I have used Vallejo Plastic Putty for blending in 'steps' such as left between the front fuselage and wing join on the Trumpeter 1/32 Me262. Plenty of thin layers, allowed to cure between each then sanded and feathered in. It worked fine and I have used it for this at least three times.

I would suggest three types of filler each good for a different purpose.
Vallejo Plastic Putty - I use for larger gaps and for 'steps', see above post.
Mr Surfacer 500 (in the jar) for smaller gaps
Mr Dissolved Putty to make us of its levelling properties. Good for very fine gaps and to help smooth uneven surfaces (of gluey finger marks!)

I've tried PPP thinned to varying degrees up to a slurry (with water) for finer fills and it seems to work great.
Disclaimer: I have just started back to modeling.

Yes, and yes! Cleaned with a cotton bud dipped in IPA, left overnight to cure.
PPP seems to be much better.

A couple of useful tips I've discovered and tried regarding old tubes of filler. I had a part tube of squadron white which had gone too hard to get out of the tube, so I cut the tube open and put the contents into a cleaned Tamiya acrylic paint jar and then added cellulose thinner to mix to a slurry which I then left to stand, after a short time reusable putty. Add cellulose to get the right mix as you do it.
The other filler was deluxe perfect plastic putty, which had also gone stiff. The remedy is to push a wooden skewer to the bottom of the tube and then add distilled water, add the top and then squeeze the tube in your hands to mix, works a treat.
I've got loads of cleaned Tamiya paint jars, come in handy for all sorts of things.
