It looks like the Pattex stuff was used to build up the gaps, and then according to the original forum post (http://www.inventosunicos.com/viewtopic.php?f=10&t=14 http://www.inventosunicos.com/viewtopic.php?f=10&t=14): "SE LE DA MASILLA DE CARROCERO Y SE LIJA" Google Translate turns masilla to "caulk," I'm not sure what it is. Would love to find out - I never thought it would be possible to take a bunch of dissimilar plastic junk pieces and turn them into something that looks like it was molded as one piece.
