Ugh, POR-15

[VTNewb]

I POR-15'd my tank. Followed the instructions to the T.

I expected rust to be on my threaded holes, since the metal ready compound causes the steel to flash rust, and they say use Q tips to remove saeler from the threaded holes. BUT I can see veins of rust that were not in the tank before I poured the sealer in. I'm not quite sure what to think. My tank looks 300 times worse now than when I started. This is especially aggrivating since I spent 20-30 minutes air drying the tank and 40-50 minutes squated over a bucket draining out non bonded sealer.

Metal ready does not cause it to flash rust. In fact it actively keeps it from flas rusting. I have a tank I treated with it and its just almost stopped rusting.
Ironically I did a tank this weekend with POR and it also had a pinhole leak in it. I thinned POR with acetone and followed none of the instructions.
I treated with muriatic acid, chased it with baking soda and hot water, cleaned it with acetone, didn't even get the water out 100%, nor did I get acetone out 100%. Then added thnner POR to it. had it gush out of the pinhole. Then I drained the thinned out por. Took thick POR in my finger and finger pained it on the pin hole from outside. Then it sat in my truck for 24 hours, and then I put it on the bike. Its got a barely visible coating, the pin hole has an outside patch sorta ... and I hope its holding up. I didn't put gas in it yet. May yet opt to coat over it again ... but It looks great. Or may patch it with JB weld.
Cool.

Well if that's the case I don't kno what to say, the tank appeared to be bone dry, and it should have been after all the drying I did. I guess I'll try to peel off what I can and try and wedge fuel filters in there.

[The Buddha]

No no no ... POR does not take kindly to any peeling attempt. No .... stop ... no ...
It will flake off with paint stripper, and that sheiete will sorta be soft and semi glue itself back on ...
I dont know what to tell ya ... acetone softens it but it will fluff up, and then dry out and wrinke on and stick back. Pathetic. It is permanent. If its not right ... you're screwed.
Heck, I consider all but the thinnest of Kreem and I mean thin thin thin veil muslin thin kreem is removable all else is toast. If its on, its not comming off.
My POR is super thin too, and I will never ever try to get it off. You're going to have to leave it alone, and put filters etc and keep it out. Do not touch it.
BTW I have a cool pic I have to show y'all ... but you would love that VTnewb. Comming up tommorow.
Cool.

I used por15 as directed.  an had no problems,.  Since it is permanent, i took my time,  if I remember right i took 4 days to do it.  not 4 days literally, but after each step I let it dry 100%   heck i even taped an old blow dryer to the tank nozzle an let it blow for hours upon hours each day. 

[VTNewb]

I'm sure I must have left some moisture in there somewhere. It just seemed unlikely to me after the air dry and blow dry.

Something went horribly wrong if your tank looks worse after the treatment.  Did you really think 20-30 mins of air drying was sufficient?  I rigged up a fan duct and circulated air through my tank for 24 hours before applying the sealer, the directions emphasized that the tank has to be bone dry.  The only thing you could do now is try another coat of sealer I guess, but you might want to contact the manufacturer and get their advice.

I based my descision on my little flexi LED light and looking at the surface.



I had a buddy of mine and my father both check and it appeared bone dry.

OK you kids are over reaching. My tank had a brown puddle of water+acetone in it. I poured in thinned out POR with more acetone, and sloshed it only to have it leak from every pore. Then I drained it, wiped it with acetone on a shop towel, finger painted the pin hole and let it dry. Its on there solid.
I guess I had it very thin so I may have gotten lucky. But following POR or freaking Kreem kit instructions is asking for trouble. I did it in 1/2 hour actual time. Not 5 mins here, 10 mins there and so on stretching into days. 1/2 hour total.
The factors that helped me I guess are ... the tank was powdercoated, so I can let acetone hit it and it didn't peel it. 1/2 hour standing in acetone will get it off is what he said.
Did it just like Kreem. That totally rocks. IMHO. Maybe it will be removable with acetone, but POR will come loose with acetone anyway so no biggie there.
I dunno ... as much as I hate dealing with acids and chemicals that have tons of lead etc in them, I am getting scary good at it. I should prolly start doing it for people just like carbs and what not. Saves a lot of grief in the end.
Cool.

We've beat the POR dog before. I am happy with my installation although I got pin hole leak while setting up.  I may search after this post and locate the other threads. I even took internal pictures using my dentist's mouth camera. I think they are still on the web.

<edited> CLICK HERE for the thread with more on this topic and my internal tank pics.

Why? Because I didn't follow the instructions exactly. The little bit of papertowel they include is for patching pin holes, etc with a small amount of POR soaked in it.

Next time I will use my pressure test gadget to locate and JB Weld the pin holes prior to pouring in the sealer.

I used a hot air gun rather than a hair dryer -- much hotter and aggressive.

I cannot imagine why you would have any rust showing, unless you had rusty water still in the crap pockets.

Srinath -- How does S&S Tank Lining sound?

We could take people's money and not guarentee anything.
But then we would have a rep to maintain. 

[The Buddha]

S&S sounds good ... yea ... reputation ... you mean its not bad enough at this time ...
Anyway I almost think I cannot ever mess up a coating job. The common theme seems to be that I put it on thin thin thin. I guess do that in future and then we'll see is all I can say.
Cool.

I'll post some after pics tonight.

You can see the horror.

I think I'm just gonna shrug the shoulders and try and jam the inline fuel filters in there.

I did find a place that will do it's treatment for $245 + shipping without ruining paint job, but that's alot of moolah.

And where's the pic Seshadri?!
