So guys, before my vacation in the Nethelands the last two weeks i finally managed to remove the anti slip panels without damaging the areas around them. It took me around three afternoons/evenigs of work.



I did the job by carving them away with a few blades (the way which i was so afraid of before!). A month ago i would have bet to ruin the work that way. I still wonder about myself...
I couldn't avoid little damages to the surface though but that's not a problem of course. Just some filler, then sanding and the job is done. For sanding around details/engravings i made a few simple but very useful tools:

As you can see i just cut some pieces of sprue, tapered them on one end and glued on a piece of plastic sheet with different wet-sanding papers, applied with super glue and grain from 180 to 600.

Finally engraved the respective grain on the sprue and that's it. For better fitting to the surface i will make some new tools with some kind of sponge taken from a nail buffer between the sheet and the wet-sanding paper. This should improve the handling and reduce the risk of sanding grooves into the plastic.
Fortunately the silhouettes of the panels are still visible which will make the upcoming masking job for applying terracotta spray for the new panels much easier. There's still one panel left to remove. The problem is that it is right under the lifting harness on the engine deck but that's not really a problem. I will build the harness from scratch after i removed it. Also HobbyBoss forgot a panel here.
Other works to do will be the welding seems. I will remove the injected-on seems because they're not recognizable as such and apply new ones made from streched sprue. Of course the stirrups will also be redone (from wire).
After all this work the crudest jobs with the upper hull should be done. Of course there still will be room for more improvements but i didn't want to make this kit a state of the art model from the beginning. In my opinion the HobbyBoss kit is nothing else than a passable and low-priced conversion for the Tamiya-Kit if you want to build a Strv. 122, A6E and so on.
