A bunch of questions??

I heard some people say the battle damage on 20th Prime (original) can be removed. How easy is it to do this? Do I need soap, water and a scrubbing brush, or do I just rub it gently with a duster?
How heavy is MP Megs compared to Prime? And does Megs seem to get heavier in alt mode like Prime does?
What is the size comparison of Armarda Unicron to 20th Prime? in terms of weight, height and width?
Anyone fancy giving me an MP Megs, G1 Soundwave with cassettes and Armarda Unicron for free? No? Ah well, had to ask.
I want to remove the battle damage from my Prime, seeing as he now has longstacks. The other questions were just for my own curiosity.
