Try an auto body filler (Bondo comes to mind as the popular brand in Canada). I've also used the Testors brand filler. Sands well and takes paint with a little primer applied first.

thanks guys. Happy new year Brian.

The Bondo Spot Putty works well. Doesn't shrink or crack, sands smooth. And you get a lot more for your money. Sticks to polystyrene, PVC pipe, ABS.

perfect putty gets good reviews, I tend to yse the warhammer stuff, as I bought loads of it

Squadron White and green are very good with nice combo of reasonable open time and rapid set. They have excellent sanding properties. The putties contain toluene which give them some bite on the polystyrene for excellent adhesion.  I use it on my wood models too for painted parts

To keep it simple I would recommend cutting the sprue into small pieces and dilute in liquid cement.  You can adjust the consistency and get it to whatever thickness you want.  Keep it in a small glass jar and it will last forever.

I number of us plastic builders use various types depending on where and what needs filling.

 

For gaps and glue seams, I like the Testors putty to use as a filler along with thick CA and the stretched sprue.  For filling low spots and rough areas, I like both Squadrons Green or White putty or Tamiya putty.

 

I use the Spot Glaze after priming to fill in pre-coat imperfections.  Spot Glaze has been safe on all the primers I have used where other putty brands have eaten or crazed certain primers.

Agreed, there is no one filler that will do every job.

 

I'll add to the list already posted a good epoxy putty, such as Miliput. You can smooth it out with a wet paint brush so sanding is minimal.

 

Also, don't forget gap-filling CA glue. Use sparingly as it can be hard to sand.

 

I tend to stay away from Bondo on plastic because it's hard to sand and prefer spot or glazing putty, (and I'm reminded I need to pick some up at the Auto parts store...)

Another vote for Tamiya

There is another that's very good for plastic, infact only for plastic.



No I have nothing to do with the manufacture or sales of this product, but I do use it and its good.

Plus it lasts a long time.

If you do not want to contend with noxious fumes, you can use dry wall compound (Spackle) . Other wise Bondo, or an acrylic putty.

I use Squadron putty and Bondo all purpose filler (basically auto body putty).

[Old Collingwood]

How about conventional household wall filler mixed with a bit of PVA glue, would that not work in areas like covering up port holes etc?
