What putty to use??

[64SS350]

What type of putty seems to work well. Using 'Feather Fill', but doesn't always stick to the styrene.

Suggestions please!

A couple people here told me that 3M's Spot Putty works well so I bought some and have had decent luck with it.

Bondo Professional Glazing and Spot Putty. It's a 2 part catalized putty, similar to the Bondo filler in the cans, but much finer in consistancy. It's about $6 at the flaps.

If you can find it, 3M Acryl Blue spot & glaze putty is excellent. It's an acrylic lacquer-based putty, extremely fine and smooth stuff--feather-edges beautifully.

That said, it's not a putty best used for really deep filling, due to its being an "evaporative putty", in that it relies on the evaporation of solvents to dry; and this WILL cause shrinkage. This isn't noticeable when filling say, a minor sink mark, or very shallow file or sandpaper marks, but for deeper imperfections, or for building up a surface you will be better served to use one of the various catalyzed spot & glaze putties. Catalyzed putties are based on polyester resin (the same resin used in laying up fiberglas boat or even fiberglas Corvette bodies. This stuff does not shrink, will adhere to styrene (sometimes it needs a bit of help on really flexible model car bodies, but that's another story and topic for another time).

as a rule of thumb you should always use a primer before puttying

that way the putty has something to bite into

Thanks for the tips, I used to use reguler glazing and spot putty, but I picked up some of the catylized to try.
