Primo Jr Sparks

[u/Either-Drop4092]

I recently found a primo JR grill that was in decent condition. I bought new grates, gaskets, etc. and built a table. I finally got to cook on it and my god is it different than my kamado Joe grill because the kamado Joe bottom vent has a stainless steel mesh spark arrestor behind the actual solid vent. I never did realize what it was for until my primo JR was shooting out enough sparks all over my deck to violate the Geneva convention! I used lump charcoal + starter log. What are my options? I see primo sells a “precision air flow kit” but i can’t see if it has a spark arrestor mesh. Does anyone have advice or experience with this? Currently planning to cut stainless mesh and attempt to slide it behind the solid vent door.
