Tank Tech Coatings

[ZCurves]

Has anyone heard of Tank Tech coatings for fuel tanks? I searched for them and only found a commercial tank servicing company. Anywho, The Rad Shop that I am thinking about sending my fuel tank to uses this coating - so I am looking for any other Zed-Heads who have used this material (Zedyone excluded ).

Thanks in advance...

Do it yourself w/ POR15

The cleaning process works very well, mine came up like new; I mean BRAND new.

I purchased the POR-15 tank sealing kit a year ago for my 72 Z. A few months after the coating was applied, I had a car starving for fuel and lacking any acceleration. Turns out the coating had peeled off like cheap wallpaper and clogged all my lines/filters, even though I had followed the instructions given. I have seen mixed reviews for this stuff, the tank must be absolutely spotless for the POR-15 to work correctly. If you go the DIY way and prep the tank yourself, I'd recommend using Red-Kote. This stuff is idiot proof and is not as finicky or expensive as the POR-15 kit that requires all the chemicals.

I haven't heard too many bad reviews, but there is a lot of emphasis directed to the prep. I dried mine out with a heat gun and a tiger torch - the sooner it dries the less time rust has to form. Also the repeated muriatic acid washes definitely did the trick. Sorry to hear that yours didn't pan out; must have been a nightmare to clean up that mess!

Yes, yes it was. I think I spent quite a while pulling strands out and re-cleaning the even bigger mess . The muriatic acid washes are a key part in the whole process with POR-15, you can never be too clean with it.

Before I had internet access, an old time motorcycle mechanic told me about the stuff he used on motorcycle tanks called 'KREEM'. I got 2 kits and refreshed my tank according to the instructions. It worked great. I believe the curing time has plenty to do with problems of it not sticking. My tank sat & cured for 2 years before fuel was introduced.

After talking to plenty of farmers around here, they are sold on the "Red-Kote' for all of their diesel tanks.

Any ideas as to why that is? What is it that makes the Red-Kote so much less sensitive to prep details when compared to the POR-15?

These posts are interesting. I am contemplating tanking my tank to a local radiator shop for the boil-out. They said that they boil-out (let it soak) for 3 days, then check the fittings (and repair if needed), then they will coat the insides with a product called 'Tank Tech' which is a yellow filmy liner. The work includes a lifetime warranty too. I asked a bunch of questions about the product, and they said they have been using it for several years with no complaints. I learned about this place from Zedyone here on the forum - he has experienced no problems either and he is pretty careful. I do value everyone's opinion here - you have pulled my fat out of the fire on several occasions.

Zcurves I am about to install triples and I will have to redo my fuel system again. I will check out the fuel filter to see if any yellow stuff came off.

I don't know know the exact reason why Red-Kote works that way. If the tank is not spotless, fuel gets behind the POR-15 liner and peels it up, like what rust bubbles do on a car paint job. The Red-Kote creates a thicker coating since it is like a syrup. It sticks to anything and can't peel off so I feel its more durable. These are just my personal experiences with using both products, since I am the only one with bad experiences with POR-15, it must of been human error in the failing process.

Cure temperature is very important on these types of two component coatings. A coating applied in the cold could take a long time to fully cure, or not even make it. If it doesn't cure fully, it will soak up fuel, swell, and fail. Ideally, the coating would get a good final stage heat soak before adding fuel. Bring it inside with the family for a day or three before installing. Leave it out in the sun. Put a heat lamp on it.

A coating applied in the cold could also flow to the low spots before it sets up, leaving thin areas. Following directions closely is important, no cheating.

I've done some work in the coatings industry. For what it's worth.

Thanks Chase. I've been told by my PO that he did the tank with POR-15. I'm hoping for the best.

Makes sense to me.
