Thinning putty?

I've use Evercoat Eurosoft automotive putty. It works great. It is a two part putty that you mix together. I've also tried Bondo Spot and Glazing putty which works well too and doesn't have to be mixed. The Spot and Glazing putty can also be thinned with non-acetone nail polish remover. Like bstrump mentioned, if the gaps are quite large, fill them up as much as you can with strip styrene first and just use the filler to fill the left over cracks.

I've used liquid glue (Testers) to thin putty a peice of foil and a tooth pick to mix it .I've read some where that denatured alcohol will thin putty as well . I"ve recently started using crazy glue mixed with talcum powder to fil gaps I find this easier,hope this helps. Redrobin

Use lacquer thinner to thin Tamiya GRey Putty.

I find the best fix for hairline cracks, narrow, shallow gaps, even injector pin marks is liquid paper.

I use the pen type dispenser, leave to cure for 10 minutes and sand nice and smooth. It does not shrink over time and can be polished as smooth as the surrounding plastic.

QUOTE: I filled in a large gap with green Squadron and after sanding have found quite a few hair-line cracks. Is there a way to thin putty, or use something else, to fill in those cracks? Thanks.

I have thinned tamiya's putty with humbrol liquid cement and found that it works well , but also try whiteout pens from your local newsagencies these work very well..

cheers mike

Scott05, for filling large gaps you could use styrene strip and liquid cement and then a thin coat of putty over top. for filling those hairline cracks and other small areas, putty can be thinned with lacquer thinner or paint thinner depending on the brand. Hope this helps.

I don't know about thinning putty, but the ideal solution would be using Mr. Surfacer from Gunze Sangyo.
You could compare it to liquid putty that can be applied with eiter a toothpick or an old brush.
After drying and sanding, the seem will be invisisble.
