Welcome back to modelling. I use the Tamiya glue for the most part though I still use tube glue. Regarding the raised panel lines, I have used very thin stretched sprue to replace the raised lines that got sanded off. The wheel hubs on most Luftwaffe aircraft seem to be semi-gloss black, this is a D-5.
Your model is progressing very nicely. I'm going to have to check that putty out.
With the bit of experimentation I did with stretched sprue, I remember I had a very hard time getting it to stick to the model. CA glue is too noticeable, even the super thin stuff when used in enough quantity to get the sprue to stay in place. Plastic cement didn't work since it melted the sprue or at least caused visible alteration to the surface of the plane. So I'm curious, particularly since probably 90% of the models I currently have on hand to build all have raised panel lines, how did you attach the sprue and/or what glue did you use?... Regarding the raised panel lines, I have used very thin stretched sprue to replace the raised lines that got sanded off.
I used Tamiya Extra Thin glue very sparingly. Attach one end to the end of one panel line and once its slightly set up lay it down along the part and attach it to the other panel line with a slight over lap. Trim this off when everything is set up. Very fiddly and sometimes requires three hands
