Grant: Thanks for your kind words regarding my 247. Yes, I agree with you and think GasoLine has some very interesting kits, and your Lancia proves it. That one is a really beautiful subject in my opinion, plus trucks (and wheeled vehicles) are always attractive to me.
It is good you did not wait longer for the Schwim wheels to join to modelling practice with your desert Sherman. As for your model there are two things that called my atention. (1) I think it would be better to paint sand color first, because it is easier to apply dark colours over light ones, and that avoid paint saturation. (2) As for your masking, it would have been easier to mask your model little by little cutting and adapting masking tape to shapes you wanted instead of masking everything and cutting after. Masking tape is easy to cut in rounded shapes with a sharp modelling knife on your cutting pad, and it is not necessary to cut the complete "piece" at once, and you can add more tape until complete. I made that before and it is easier than many can think. Anyway do not get my words wrong, and I am looking forward to seeing your Sherman complete soon.
Finally as for your Schiwm wheels replacement, I strongly suggest to get one VW Type 82e because it has TWO sets of wheel hubs (with or without hub caps) so you can use the standard one (without) for your Schwim tires and the other (with hub caps which implies more civilian look) for your VW. Actually the Type 82e is a very "cute" kit that will give you a very good time when you make it. I did past year and it is really "lovely" model.
Darson: The 502Ab oils are a new range of oil colours for modellers. Do not get me wrong and do not think the product itself is something new or revolutionary, because oils are oils, I mean 502Ab are exactly same artist oils we always had, but what is new is the "colour selection" which is very intuitive for military modellers and helps to pick the right colour to use.
