Gas Tank Sealer

In simple words, a gas tank sealer is a chemical used in fuel tanks that prevents rusting of iron or the corrosion of other metals. Gas tank sealers are widely popular for both professional and nonprofessional purposes. Gas tank sealers are, at times, used in combination with other chemical products which come with the brand name, Aqua Klean and Rust Blast. When a metal is coated with this sealer, it forms a protective layer on the metal and prevents it from corrosion. Subsequently, it also repairs broken joints and fills up small holes. Hence, it strengthens the structure of the metallic substances or pipes that it is used to repair. Gas tank sealers have various uses, such as making cubicles for chemical batteries, strong adhesives, mounding pipes and hoses, for repairing broken pots and pans, ceramic crockery and so on.

Gas tank sealers come in different brand names and their applications vary from fuel tanks, diesel tanks, oil tanks and also water tanks. Because of their wide usage and demand, more sophisticated and efficient gas tank sealers have been designed, and some of them may even be used on steel, aluminum, and fiberglass tanks.

The stepwise process of using a gas tank sealer:

  • The gasoline and oil should be eradicated by using the organic substance, lacquer or acetone. These should be carefully poured into the tank, after which it must be rotated multiple times to ensure that the solvents reach all sides of the tank. The resultant mixture should then be removed from the tank. This process is needed to get rid of harmful substances and contaminants.
  • Before coating the tank with a gas tank sealer such as Kreem, for example, the older layers should be scraped off with the help of a paint remover, sand paper or methylene chloride.
  • Several drywall screws have to be dropped into the gasoline tank and shaken so that they come in direct contact with all corners of the tank. This purification technique extricates any non-coagulated particles of rust within the tank.
  • Now, for further cleanliness, the tank is rinsed out with approximately a pint of lacquer or acetone thinner. After this is done, we have to wait for some time and allow the solvent to dry. An airline pipe going right into the tank can also fasten up the drying process.
  • A layer of masking tape or duct tape must now be applied to any holes, porous areas or ridges. This will prevent any of the gas tank sealing chemical from flowing out, aiding it to accumulate and solidify over the hole. Now the outlet ports must be filled with putty or Play-Doh. Then the rest of the chemical must be mixed.
  • The two mixtures should be thoroughly measures and mixed in correct proportion for best outcomes. The mixture should be blended for at least a couple of minutes so that no portion is left unused.
  • Now the mixture is ready to be poured into the tank. Pour it into the inside walls of the tan cautiously and then use a rubber band and Gladwrap to stick down the filler cavity without any delay. Failure to do so will give poor and unsatisfactory results.
  • The tank must now be swirled around in different directions for a number of minutes in order to get a good and homogeneous layer of the gas tank sealing chemical over all surfaces.
  • Then discard the Gladwrap seal, the filler cap, and drain out any residual substances. Allow the container to drain in an upside-down position for some time.
  • Blow a stream of air into the gasoline tank so as to clear any traces of the gas tank sealing chemical from the filter.
  • Scrape off remains using a sharp blade at this stage, and do not use the tank before exposing it to a temperature of around 80°F for at least 8 to 10 hours. However, for alcohol-based fuels, 3 to 5 days’ time must be given before reusing the tank. In such cases, the tank can be kept at normal room temperature or at a temperature of 120°F for a whole day.
