Thanks for the support guys! And all the feedback and time to look this rather "exotic" model for many of you here.
Now the answers, not in any paticular order:
Chris: Thanks, I really enjoy the time spend building chilean models, not only because itīs my own Motherland, but for the challenge to my skills to get a more or less accurate rendition.
Koen: Counted your vote, thanks for your time. 3 to UN white, 1 to 3 colour then...
Carl: Thanks buddy, 4 to UN white, 1 to 3 colour scheme... I thinks all the sanding took about 4 days (1 hour per day) to get a smooth surface....
Olivier: thanks mate, your opinion itīs of great value (as are the one of everybody here), but yours itīs important since your level of model building (as Mother). Youīre right, but I wasnīt able to get the right ones with the plastic rods I had here...my nearest LHS didnīt have any of the right diameter in stock, and didnīt want to put it on hold till I get the right ones....donīt like to see unfinished kits you know

Scott: Thanks for your words, yet to figure how to do the new 60mm gun before to go into it. And, more important, I donīt have the old Dragon M-50 kit to do it, and cannot afford to buy all the different Shermans from Dragon to get appropiete parts for only 1 final model...since Iīm not into WWII kits, all the leftover parts will be of no use to me.
But any feedback of your current build would be helpful (on the kit building technical side, since I have a bunch of pictures of that particular tank. If you want some I can help you, send me a PM)
Thanks for your time and feedback mates, really appreciate your opinions
Cheers
