Cleaning out your sealcoating tank
Well the only way i know how to clean out a sealcoating tank is to get in side the tank & scrap the sides & bottom of the tank. Use what ever works best for you.
I myself never got inside a tank before, I paid someone to clean it for me. & the best time to clean out your tank is when it's cold out side or when the sealer is solid not at a liquide state (So i was told)
