To use the wood decks properly, you have to remove all the moulded detail - like the 'planking', and make a flat surface. A lot of these AM products are self adhesive. The thickness is about 0.25mm, so in 1/350 about 87mm, or just over 3" - they can be tricky to apply.
I used the Artwox Model set for the Revell Emden - made a real mess of it & worst of all ruined the surface finish of the wood, defeating the whole object of it! Not one of my best moments!!! Never did finish it! I sourced it from China - it cost about the same as the base model, I remember.
They can look superb, but take a lot work to fit - not, I think for a beginner!
