My experience with POR-15 is that it is very runny. Is this the case with the tank sealer? I'm afraid the stuff will just leak out all the pinholes.

it did not run out of the small pin holes on my tank . clean the out side of the tank and put duck tape on the out side

I fellowed the directions and POR-15 worked great, My gas tank on my snow blower had a 1 inch long crack plus a couple of pin holes. The blower was stored out in shad all winter long, this season was long with 50 days of below zero.

I did not get good results with this product. I followed the instructions to the letter. Finally had my bike tank professionally restored.

well it was runny my husband bondo'd the areas that needed it, but all in all did the job it no longer leaks

I used the tank sealer on a rusty 40 year old tank and it worked perfect , yes its runny . put some duct tape on the outside and seal the inside first , the remove the tape and sand the outside areas and brush it on the outside .. its been year ago now and no leakes.. it drys very hard like glass= ceramic... it worked for me !

I had my tank acid boiled. The put a little jb weld on the holes. Body filler may work. Then I used the product. Worked well and still see it running around town

Mine is very touchy about set up - gaskets placed very precisely or it will leak, tiniest bit of air left in filter makes it noisy. I frequently have to do it a second time to get it all right - granted part of that is my very limited attention span when doing it combined with the fact that I only tear this filter down about 4x each year for cleaning and I don't always remember all of it's little quirks. (Yes, I know it says more often but I'm running it on a tank with a small bioload). However, I've had this filter for about 15 years now and the only thing I've had to replace is gaskets and a clip that holds on the inflow pipe. I think it does an awesome job, but it can have it's quirks. Mine is very touchy about set up - gaskets placed very precisely or it will leak, tiniest bit of air left in filter makes it noisy.

Sometimes I have this problem if I don't completely release all of the pressure. If that doesn't work, use a little oil and run it as close to the seal as possible.

Don't use this. It won't hold up. Try caswell plating product. Red kote will clog the holes if you keep the holes plugged while coating the tank.....you will fill with gas 3 months later and think to yourself where is all the redkote then notice your leak....red note did not work for me

It will seal it with no problem, but you will need to put something in, or over the hole like tape, etc as this stuff is very runny out of the can. I cant live without it overall.

I would think you need to clean the inside with something because the POR-15 paint won't stick to the penetrating oil. I used Muratic acid but it won't do the cleaning part either but it will pit the tank for good adhesion.

That is the design :) No leakage for me yet, but you have to make sure the seal is in properly (it comes out for easy cleaning) and I'm sure it would depend on what you put in there. Something really juicy may leak

As you, have burned up several sealers- but have found this one to be the best so far. Can run continuously, with occasional cooling down of the sealing strip. So far happy with this one. Hope you are as satisfied with yours as I am with mine.

Are you using the 1lb small gas bottles? If so the may not be sealing good. But also the regulator could be leaking. A solution of soapy water in a spray bottle will find the leak.

I can't answer that question because, following the instructions, I drain the tank after use, eliminating moisture buildup. However, after using compessors for over 60 years, I can tell you that as long as the welds are done correctly and the fittings are tight, any air leak is extremely slow.

Mine leaked. You might need new gasket rings. Mine always broke and didn't seal completely.

It worked find for all the things I used it on. Are you sure your tank was full enough to put the presure out? Hope you figure it out. Smiles, ~Smitty~

I've had mine for months, the gasket seems fine. What can happen is that air escapes if the seal on the compressor, for lack of a better term, is not seated properly. I run the bead that contacts the container under the tap to moisten it. This insures a proper seal with no air escaping. As an aside, gaskets can be hsd very inexpensively.

yes, you do. The tank has to be removed and thoroughly degreased. Use POR-15's Marine Clean mixed with hot water for degreasing. Then the tank should be rinsed and drained well and de-rusted before lining it with POR-15 Tank Sealer. POR-15 has a rust remover product but I've been using Metal Rescue. POR-15 Marine Clean and Tank Sealer are awesome products - to get great results it is a lot of work but worth it to save a tank.

I hope you get an answer since I was wondering that myself. I left mine in but used it again in the next day or so. It was always ready to fire. I think these other folks are correct because I am sure it would eventually leak out. I like the suggestions for enhancing the seal.

I have had great success with the Caswell tank sealer in metal and Fiberglas tanksI am not sure what plastic tank you plan to treat but if there is bubbling under the finish could be other problemsWhat make, model of motorcycle tank do you want to treat and is the tank painted?Or is it a tank like the Malcom Smith Desert tank where the color is transparent and moulded into the tank?Thanks and please get back with me
