i was wandering how the modelers get their engine parts and trim to be that shiny gold or chrome. if u know what they use please tell me.  

You can use "bare metal foil". U can find it at just about any hobby store.  

The chrome foil works great! Go to www.baremetalfoil.com to check it out! You cn also get it from www.micromark.com which is a modelers paradise if you need small tools. I also use the alclad 2 chrome paint which is awesome and the closest finish I have ever seen to chrome. Go to www.alclad2.com to check it out! Hey,I should be getting paid for plugging all these sponsers! Just kiddin,hope this helps you out !!
