Here is a picture of all the extra stuff you need to seal a tank with Pro-Seal. This is stuff beyond what you all ready have. 1.) See through plastic cups. 2.) Scale that can measure 1 gram or less. 3.) Tounge depressors and pop cycle sticks. 4.) low tack masking tape, electrical tape. 5.) M.E.K or Colmann feul. I have both for now. 6.) Pro-Seal of course 7.) Napkins or papa towels. 8.) Rubber gloves.
