IPA Dillution

[katotter]

Hi all,

I recievd my first bottle of IPA (PROPAN-2-OL) which I had to order because no one in my dof town keeps it in stock. This is what I recieved.

I read that if the dillution is not true and it is too strong you might damage the paint and other surfaces. My question is, how do I get a true 1:1 dullution per vollume or am I just trying to be too technical, is 50ml water to 50ml IPA sufficient? Do I use regular tap water or RO water?

Please help a chemistry noob.
