Starting to get back into it after the paint experiments. I have to admit that I got pretty discouraged there for a while about all the variables with PPG paint mixing. Im going to get 1 more sample before I get the gallon, (it would appear Im still not through in this area, can you believe that?)Assuming I get the color that makes my little mind happy, and I can prime and shoot the topcoat within the window, I am guessing this would be an appropriate time to educate myself on the different types of reducers and hardeners. This is what I have: MP170 & MP175 cat. 1.3 - 1.5 mm tip MP182 surfacer and MH166 very slow hadener. 1.6 - 1.8mm tip MTK with MR 186 med reducer and MH169 very slow hardener. 1.4 - 1.6mm tip I am waiting for the right weather to do this, in the 80s or less and dry. Are there the correct types of hardeners and reducers, (fast, med, slow, very slow, etc.) for the shooting conditions? And under what circumstances would you use one speed or type of hardener or reducer over another? These 3 different processes call for HVLP tip sizes from 1.3 - 1.8 mm. Does this really make a difference when spraying? Could I use a 1.3 for all the spraying or should I abide by the product sheet and order up some tips? Also, when do you know when the paint is reduced correctly for spraying? Do you folks reduce to the standard on the MTK sheet, or for higher solids and what is the difference there? Thanks for all your help, especially you, Rod and CNKS,
