Automotive News Mixing Paint Accurately New
The feedback that I get indicates that there is confusion about mixing ratios. We want to be as accurate as we can with out causing too much brain damage.
Common mixing ratios are 4:1, 8:4:1, 2:1 and 4:2:1. Let's use 4:2:1 as our example this is a common mix ratio for urethane clear. It means 4 parts of clear to 2 parts of reducer to 1 part of hardener. That means 4 ounces to 2 ounces to 1 ounce or 4 gallons to 2 gallons to 1 gallon or 4 buckets to 2 buckets to 1 bucket.
Using a graduated container pour the clear in to the 4 then the reducer in to the 6 then the hardener to the 7 then stir.
Before you leave the paint store make sure you know what the mixing ratios are and know what kind of reducer/thinner you should be using
I would like to see all paint companies have this prominently written on the label but it isn't always there so ask the paint store employee he should be able to provide you with a product data sheet
