Hot Rods Painters: can I reduce mp 235 sealer with mr 186 reducer ?

Both omni products, both urethane, yet they want a different reducer, I dont have it, want to shoot today. shall i test a bit and see if it mixes? I would like to reduce the sealer so it lays down better. thanks

 

Omni MSDS sheet shows 186 as compatible with 235. I searched MSDS omni 235 for the info.

 

Thanks. I looked at data sheets that gave a 4 digit reducer #, and googled but could not find the answer, thanks again
