Anyway ... Kreem is just misleading in their instructions and what they give you in the kit ... Just enough acid to maybe do 1/2 a tank, Enough acetone to do 1/4th a tank, and enough Kreem for 5-6 or more ... The coats should be thin thin thin ... 3-4 coats ... none thicker than 1-2 thousandths ... and all put together less than paper thin ... else it will behave like its a separate entity ...
Basically, get acid in .. treat the rust, get the acid out with water flush, then make sure its neutralised with baking soda ... then get water out with hot hot hot water and drain it and use and a towel ... then MEK rinse to make sure water is out, then Diluted Kreem ... and over and over and over ... and maybe after 3 coats, let it csure out fully and try scratching it with a screwdriver ... if you scratch it ... good, if you take off a swatch with your screwdriver ... Oops ... put the thing under a saw and cut it open and get the kreem out ...
Anyway thought I'd show and tell ... This is the 3rd crappy Kreem job I am cutting open to fix ...
Cool.
Srinath.

That's why I hate that stuff. :x If (when) it peels off in chunks it has a habit of immediately stopping up fuel sumps. Not bad when you can pull off the road, but not pretty when it happens at 35,000 ft.
My favorite treatment for steel fuel tanks involves ball bearings, silica blasting sand, water, alcohol, and elbow grease.
I prefer Dunkin Donuts. KK has too much sugar for me - gives me the shits. :? :lol:

I have seen tank treated with Nuts and beebees and diesel ... put a gallon and put a handful of nuts and beebees in it and shake till you are too tired to breathe ... then dump it and voila ... But those rust ... yea keep it filled up blah blah ... still the roof will be 1/2 exposed and will rust ... then of course there is the obvious problem with the GS where its crap pockets will trap the nuts/beebees and you cant get them out really unless you have nuts tied together and then they dont have the full mobility ... etc etc ... Kreem is great but you definitely want to do it right ... acid in, acid out, water in water out, and Kreem ...

Hey Srinath,
How much do you charge to Kreem a tank? I've got an old one I'd like to get coated and don't want to mess with the acid and fumes and such.

Sorry but do not waste your time with the Kreem stuff.
I have used the 2 part epoxy from Caswell with good results.
http://www.caswellplating.com/aids/epoxygas.htm
To prep the tank use OSPHO
http://www.jamestowndistributors.com/ak/Cleaning/Paint_Prep_Cleaners/Metal/OSPHOQ_OSPHO_METAL_TREATMENT_QT_12_CS_NO_AIR_PHOSPHORIC_ACID_UN1805_933_11107_prod/index.html
If you follow the instructions to the letter you will have great results.
Just a note if you need to sand and paint the tank go ahead and get to the point of painting the tank before you use the epoxy sealer just incase you spill the sealer on the painted surface it is a pain to clean up.

Being that there is rust attached to the kreem it is an issue of bad prep work in that the kreem appears to have worked but the rust that was not removed did not allow for the kreem to stick to the tank. Either the rust was past the point of repair of the tank was not prepped properly to allow for the kreem to work.

Yea ... poor prep ... acid in, all rust out ... which is where the failure occurred ...
The problem is not really the person doing it, it's the instructions and the quantities in that kit ... The 2 part epoxy stuff ... I sorta refrain from that ... cos if you blow the first step ... or any step ... the reversal is near impossible even slicing open the tank ... I have reversed bad Kreem jobs wihout any problem ... heck I can remove the entire kreem coat in a tank without affecting anything else ...
This tank was leaking, and dented ... so I though I'd do my favorite thing ... slicing open and de denting it from the inside ... it anyway had to have a serious weld session to get anywhere near air tight ...
Xtalman - Kreem will be $50 and shipping ... If your tank is going to spring a leak when I drop acid :lol: ... I'll test it and weld it up and continue the kreem. I came up with a way to pressurise the tank to test ... whoo hoo ...
And conanlloyd your tank was sweet ... in and out, its derusted, has a 1/2 bottle of oil rolling around in it and its getting shiny black powdercoat ... no worries ... When it gets back, I'll get the oil out, wash inside with Gas, then MEK, then coat ... You know the rest ... I'll PM you if anything pertaining to your tank shows up ...
BTW a dented tank ... if you give it the opportunity :lol: It wants to be an undented tank ... in many cases ... steel does have a memory ... albeit a faint one ... you take a dent and tap it once with a steel rod in the other direction and it nearly wants to pop back into its original shape ... :lol: One of the dents I had ... it popped back when I sliced the tank ... the vibrations from my jig saw was just enough to have it pop back to original ... I had to cut it cos I had to get this sheite out ... and scraping and sanding might be the best ...
Cool.
Srinath.
