Make sure the surface being primered has been prepped.....this means all the crude bodywork has to be done (this is before the blocking filler primer K36 or K200
If going down to the metal, do use the metal prep......(this is mostly a 30:1 water to phosphoric acid mix....
DO rinse it off.....and do dry it (wipe with tacky cloth after dry...)
I also like to wipe the surfaces down with reducer.....so fish eyes are held at bay
the mixture is 1:1 for the primer and hardener....
I like to scuff the surface before shooting....
Some people like to run a bit of reducer in the primer-hardener mix so it sprays on fluffy and has a sandalble surface.....this is good if you plan on future bodywork....
good luck
