I was wondering if anyone would understand why I’m getting what looks like dirt like particles under the finish. I seem to have a good finish layed down once it drys throughly other than the particles . Use if a Apollo power 5 with 7700 gravity fed gun and 1.5 needle. I’m just spraying test panel but was wondering if the panel should be raised off surface instead of flat on it maybe air bouncing back on panel . Tried thinking with ww fluid and it did help a little. Any help would be appreciated.
