Good choice .
Been addicted to that 2X forever .
I've commented prior in other threads about Tamiya Surface Primer being great stuff but the price has become insane .
I have one can left from a bunch I bought years back and won't be buying any more of the stuff .
When you're finished spraying that Rustoleum immediately pull the spray cap off , invert it and fill it with turpentine .
Wick the turp thru the spray nozzle with a paper towel until it flows out completely clear .
You can use min spirits but I found turp is more aggressive and works better .
The key is to clean it out immediately every time .
Acetone will work also
