those are just msds sheets, they just tell you that you shouldn't drink or smoke this stuff because it may ruin your sex life for good. they don't tell you how to use the product. contact the company direct and ask for teck sheets or data sheets that tell how to us their stuff. :)
they say my name is Jay

Welcome to the board.

You need to have a little more patience as most folks here are 9.5 (or more) hours behind you ;-)

I read your question a few times and I can't understand exactly what your issue is. You have a base coat product and a clear coat, correct? If you are concerned specifically about the hardener (or activator), there's high probability that the same hardener can be used for both base and clear. The tech sheet may tell you to buy different hardeners but (my opinion) that's usually to help generate revenue.

If you are adding hardener to your base, it's usually only about 5% of the mix. In most cases adding hardener to the base is optional, but sometimes desirable. You will, of course, need reducer for the base -- if they didn't give you that you need to get it.

google chrome or how to spray chorme base coat.
i've read some where online, that, you have to paint what ever your doing black with base/clearcoat. when the clear is set up in a few hours or so, then you spray that chrome base coat, and then clear it.

so it's the same thing, top coat means base, clear, or single stage. undercoats are your sealers, primers. so when they say top coat, they're refering to the base/clearcoat. that's all. but really google it, from what i read, in order to get it to look like chrome you have to spray it a certian way.
