Sprues & glue

I've made some up with the dregs of a bottle of Tamiya extra thin but haven't used it on a kit yet. Testing showed it to sand just like the kit plastic, and you can vary the consistency by changing the glue:sprue ratio, so you could make it brushable I'd guess.
I've used this method in the past ( using Humbrol Liquid Poly ), and it works reasonably well, what I found was that it didn't keep well, it hardened after a few days in the bottle. Perhaps Tamiya Extra Thin may not do this?

I have heard that as well but it is easier to get Mr Dissolved Putty instead or something thicker, Mr Surfacer 500.
Sprue Goo (as I call it) is excellent stuff. Depending on how thin you mix it it can be brush applied, If you use the sprues from the kit you are working on in effect you are filling the gap with exactly the same plastic - excellent news if you have to rescribe. It is also a very strong filler. It doesn’t suit all applications but done right gives exceptional results.

Hi Paul
I prefer a water based filler such as Deluxe Materials Perfect Plastc Putty. It can be thinned with water to the consistency you need. It is white so you can easily see where it has been put. Being water based it cleans up easily with a damp cotton bud etc without damage to the surrounding area. It sands back easily when dry. It will sand back to a feathered edge which is useful for getting rid of 'a step' along a join.
Sprue Goo is used by many but care is needed as being based on a fairly aggressive cement it can damage surrounding detail and can only be cleaned up by sanding when dry/set. Spue glue also does not adhere well to resin or PE.
As Barry mentioned Mr Surfacer 500 makes a useful filler.

That sounds like what I am after. Where can I get some? Thanks.

I haven't checked but John normally has it in the shop. I use it as a brush on filler too.
The Mr dissolved putty as mentioned by Barry earlier is very much like a thin sprue glue. I find it good for running into thin seam gaps, where it does a bit of filling and glueing in one go. I don't use it much though and if I was only to buy one it would be Surfacer 500.
I use Perfect Plastic Putty, as well. In this YouTube Video, scoot along to 8 minutes, and you'll see how Phil Flory uses it...................
and John has it in stock herehttps://www.scalemodelshop.co.uk/product/40ml-perfect-plastic-putty-deluxe-materials-bd44

It is very thin and good for fine seams and for where you get a rough surface as it is very self levelling. It’s a great product when you need these qualities. Mr Surfacer 500 is thin I and does those gaps not suited for MDP. I also use Vallejo Plastic Putty and between these three you can do just about all the filling jobs you need.

Agree with Barry on Mr Hobby Mr Surfacer.
I use these
Mr Hobby Mr White Putty (tube) good filler for larger seams.
Mr Hobby Mr White Putty R (tube) more smoother & slightly runny
Mr Hobby Mr Surfacer 500 for slight imperfections finishing over the above two.
Great point about all three they are very like the hardness of plastic. When sanded,
especially wet & dry sanded, they debrade equally. All three especially the putties
harden quickly.
I use Vallejo Plastic Putty in small seams where I can run a wet finger down the joint
& it is finished no more work needed. Problem with Perfect Plastic & Vallejo is they
are softer than plastic & when sanding they wear away quickly & also a tendency to
crumble. None of the Mr Hobbie's fillers do that they feather edge.
