Funny thing is properly specified marine ply MIGHT not actually be waterproof if the plies are thick enough. Damage is done by the ply swelling enough for the glue bond to break. I was just pointing out an common failure mode, YMMV.

In a boat, the process is tuned to keeping the liquids on one side of the stratum, not much attention to keeping the inside watertight.

We now return you to your regularly scheduled discussion

1. Removed custom steel undertray. (-9.65 kg, but I will not count it in the general log, because it is not part of the original car equipment.)



2. Did fitment check with PVC model. It is almost perfect. Created holes for factory fasteners.







3. Put OEM plastic undertray until I will build custom one.

How does it compare to the OEM plastic undertray regarding weight?

Had not measured, but it should be less than 1 kg - I can hold it with a single finger.
OEM is more like a dust cover, while the steel one is more like a shield.

Next time will do proper measurements for OEM.

Not sure to which extent it would be worth as a dust cover. Most likely it was added to smooth the underbody. Can you bend it with your bare hands?
