Hello all- I just ordered a "Aquacraft Rio EP" and the hobbyshop was out of 'GrimRacer Speed Grease Cable Lube" what can I use instead. I have been in scale boating for years and alwaus used car dif grease in my stuffing boxes since there is lower speeds (I guess I never had any problems) but have never had a speed boat of any kind aand that grease may not work in this case. Any help would be appreciated dont want to destroy this thing just yet [8D].
