Guys,
Just wanted to know what Putty / filler you use on your foamies.

I have seen a lot of people abroad use Lightweight Spackle
Something like http://www.dap.com/product_details.aspx?product_id=61

Know of any good equivalent stuff, in India ?

search foam putty in ebay.com. you will get for around 10 or 20$ i guess.

Well yes, Ebay has the follwoing:
http://www.ebay.com/itm/FOAM-PUTTY-Woodland-Scenics-16-ounces-1447-/220950189800?pt=Model_RR_Trains&hash=item3371a856e8

Interesting that we dont have a comparable product in India  !

I have seen people using something called Tuffix in Pune. but didnt found it here in Kanpur

Is that not PolyUrethane though ? Must be heavier than putty.

this is the tuffix....
