This is for the guys who have experience using the business-in-a-box cheapo model from StarSeal of Ohio. Some of the "senior" members seem to forget what it's like to start out, so please keep your flaming about this unit to yourselves because I've already seen it in just about every other thread where the trash-pump units are mentioned. We know you don't approve of those units.. but some of us are not wealthy enough for the professional units. I live in the Northeast and will be using a coal-tar emulsion sealer. I want to know from the guys who have the square-tank units how you mix your sealer. What additives do you use? How much water do you add. Can these machines really take sand and still hold up for a season? I'd be satisfied if the pump made it through half a season before needing replacement because they're so cheap. Someone mentioned that with these units it's better to seal the drive and broadcast sand after. How would one do this??? You can't walk all over the drive after you've sealed it! I can't figure out what he meant by broadcasting sand after you've spread sealer. Also... tell me please, what hand tools and other accessories are absolutely necessary at start-up. Remember.. I can't afford to go out and buy the best ANYTHING yet.. so be reasonable. What's the best brooms..spray nozzles and setups.. blowers at a bargain..etc. Also, for residential driveways.. what do you guys charge? Thank you in advance for the help!
