had an issue over the weekend while painting, that i couldnt figure out i would get solvent pop in random spots on the first coat of clear and on the first coat of base would texture up funny. had more than enough flash times ! ive been using 700 waterborne in a plastic usc handy sprayer after talking it can melt soften the plastic and release the mold agent and contaminate! also use a good quality well know solvent borne wax and grease remover i was running low on 710 and got some grow automotive its what was at the paint store it might have caused me problems as well. and was told to use 700 waterborne first then solvent havent had problems since, just wanted to let some people know so they didnt have issues like i did. thanks again to the SPI team for making excellent products
