Sealing products available at Panduro?

[starfish]

Hey folks,
do you know any Products available at Panduro which can be used to seal ponies repainted in acrylics? (Panduro is a Swedish chain of stores, we got one shop here in northern Germany recently, at the moment they are the only good supplier of crafty things in our part of the city -.-) Or a European shop on ebay for that kind of things?
I need something that neither cracks nor gets sticky. Preferably not too toxic. They offered me an ordinary matte varnish, but it's made for painting wood, the other option was some spray-on varnish, but nobody had a clue how it would work on plastic ponies
Thanks in advance!
