Do you sell a sealer for a R.V. plactict or whatever a waste holding tank is made of ?

you would have to contact them direct, this sealer is for metal gas tanks and I don't know if it would work on plastic.

I have a toyota camry 1997 and the gas tank started leaking drops of gas when my car is on. Will this seal work on my gas tank? its a metal gas tank

Yes and no it could definitely but I would be worried about the hole getting bigger after rust or further cracking depending on what happened . I would suggest putting some tank safe jb weld then using this. for your gas tanks you will need the 2 quart version of this . here are some links to read up on it I hope it helps. https://www.kbs-coatings.com/tank-sealer-flow-chart.html https://www.kbs-coatings.com/how-much-tank-sealer.html https://www.walmart.com/ip/J-B-Weld-8217-J-b-Autoweld-Gas-Tank-Repair/52510066?wmlspartner=wlpa&selectedSellerId=1330&adid=22222222227045949347&wmlspartner=wmtlabs&wl0=&wl1=g&wl2=c&wl3=95409016250&wl4=aud-261800281660:pla-217979583890&wl5=9018402&wl6=&wl7=&wl8=&wl9=pla&wl10=100362769&wl11=online&wl12=52510066&wl13=&veh=sem

A lot of answers on the FAQ say that it covers 3-4 gal tank. i have a 5 gal tank, do i need two cans or just one?

I used 2 cans For my 5 gal tank

can this product be used to repair a crack in the bottom of a 1200 gallon plastic water storage tank?

I used this after the rust blaster to coat the inside of a motorcycle metal fuel tank and it worked great, but for your 1200 gallon tank, I don't think this will help at all as it is more of a coating than a crack repair and you would need way to much of this product to even try. I would search for another product for your repair.

Seals well

Puts a nice thick coating on interior of the fuel tank. Used on an old motorcycle tank after cleaning to take care of rusting.

Gas tank renewal

Easy to use and function well,spread out pretty even and stuck to the inside of the tank with ease dried in a fair amount of time and held up strong looks good a little pricey but worth it

Time will tell

Used as part of the three stage sealing for a gas tank. This was an easy process. There are ample videos on the internet that share how to use this product. There appears to be product left over which I will likely use on another gas tank project. It is still early in the process and I hope this product will address the issues I have had with a rusty gas tank contaminating the fuel delivery process with a combustion engine.
