Hi..great problem.. I do know some companies make in inner chassis dirt guard ..I ran a few times in Georgia..and the red dirt what i call clay made cleanup a mess..I just took cling wrap and gave it a few wraps.since none of my electronics get above room temp or outside temps i was fine..also heard Zmaxx works wonders except on carbon fiber NO NO..also a no on electronics but great on bearing..just a blast of air and 99% of dirt clay was gone..That's my suggestions.. Or make ur own chassis guard from plastic window.. 7 minutes in 325 degree oven wrap it over or chassis and makesure u can get it back off .. ur own guard adds weight not sure of lifesapan but better than not..
