DAF torpedo front truck and front steer truck

[Finster]

Peter,

This will be a very unique truck and you are doing an awesome job making it. I am also interested in this technique of building cabs with cardboard. You've answered a few of my questions already with your posts but I have a lot more. So here goes:

Based on the photos are you using wood glue to initially glue the cardboard together?

PU-lacker is that the standard polyurethane that is used to cover wood items and you are brushing it on? How many coatings?

You said the roof is 3 layers, do you try to make the cab a certain number of layers or thickness?

Do you wet the cardboard at all to aid in bending/shaping?

What putty or filler do you use?

Thanks in advance. Sorry for so many questions...
