The only way to get the cromelike finnish on Techlines Cermakrome is to use a vibratory polisher. Is could work to do it by hand also, the coating is mainly based on aluminum particles så use the same tecniques as for polishing alu, but you cant beat the finnish you get in a vibrator.
Not sure what you mean by polishing it after a week, but out of the oven its more like a beige matte surface that need to be treated some way. An alternative way would be to glassbead blast it at very low pressure to get a pretty nice finnish on it, use large size glass for better result.
And yes, it can handle every chemical you got in a car
