POR-15 Tank liner PICS
« on: June 26, 2008, 03:30:42 AM »
So my tank had not been well maintained, I had rust inside it, not huge cornflake rust... but rust all the same. Which I am sure was the culprit of my #2 carb always wanting to overflow in the past. I had looked around a bit for tank liners and with not too many nice things being said about "Kreme Coat", I avoided that brand, There were good things said about "Red Kote" and "POR-15". I choose to used "POR-15", here are some pictures of the tank before, petcock disassemble, during and after pics. I feel it went on well although it did take some time, perhaps I am just picky or slow :)

Also I would like to note, it is quite tricky to get decent shots of the inside of the tank.

- The before pics of the tank, rust was mostly on the botton seems with a bit of scattered spot rust. The bright orange you see just inside the tank looks like a PO had some paint overspray go inside the tank.





- The petcock disassembly. This was fairly dirty and as you can see the screen and bowl had caught some debris











*** A quick aside here, is the petcock filler tube supposed to be SLANTED like this? ***



* This really stuck me for about an hour, I was really trying to figure out how to block of the Petcock holes for the process. What I ended up doing was cutting some fuel line flat out, putting the petcock attachment screws though it with some metal washers to apply pressure to the middle hole. For the gas filler neck I used "Tuck Tape", Love this stuff :)










- The Kit, Stage 1, 2 and finished product. I, like tintin coated the gas filler neck to offer is some protection later on  from gas dribbles. I will be painting the tank and side panels so the bit of spillage I got is not a concern.

















*** This is what I had left over at the end, about half I figure ***



- The finished product!





Gave good coverage I believe, I don't really have a reference though :)
For time lines:
- 1 - 1.5 hours with "Marine Clean", turning turning turning. Got some rust out, took off the orange overspray. Seems quite basic and will dry the hell out of your hands, not kidding. Wash discard fluid was not the much a different color then the original.

- 1 - 1.5 hours with "Metal Ready", turning turning turning again. Not a BIG change from the last stage, definitely a bit cleaner though, more spot rust removed, still some on the seem lines but well reduced.

- 1 hour on the "Sealer", turning turning turning.... this is the last time... right? I retrospec I think I may have been rotating a bit fast, GO SLOW, real slow, it will help. I got the bulk of it drained out and then had to leave to shuttle people around, always a inconvenient time :)
 I propped it up on an angle where it couldn't block the petcock area and left for an hour. Came back and rotated and drained it a bit more. I have it standing up *gas cap up* to cure for the 4-5 wait now.

Hope this helps some of you :)

Y'know.................it seemed pretty clean before the final sealant step. Why didn't you stop there? I think all these old tanks have a little corrosion inside.

Man, your starting point is about what my nicest tank looks like inside, and I've been running on stuff like that for years.  It looks like a lot of that crud in your petcock was actually paint chips from the overspray and not rust.  Plus, I doubt any of it was making it through to your carbs (might wanna check the clearance n your float it could be hanging up on #2).  POR15 is good stuff, though, and you'll never have to do it again, but I doubt that little bit of rust was causing you any problems.

It took me the better part of a weekend to seal my tank with POR 15. The biggest time killer was getting it dried out after the rinse phase. Yes, it took a long time, but doing it right is worth it.

just covering my bases on this one guys, spending this much time (and learning) to clean up and rebuild my carbs, I don't want to have it hitch up on a dirty tank  ::)

I wish I would have used POR-15.  I used Kreem coat and it sealed it but looks terrible.  Yours came out perfect! >:(

Not to beat a dead horse but I just noticed my 4-year-old Kreem liner starting to peel last week. I was completely anal about prepping it, cleaning it, everything by the letter. So next time I'll be using POR-15. Thanks for the pics! It looks great.

Nice post with pics and all.  And yes, that petcock tube is supposed to be bent like that.  You did a nice job.

Great writeup.  Do give us occasional progress reports as to how it's holding up.

This thread just reaffirms my second-hand opinion that POR-15 is clearly the far superior product over Kreem.  Never seen a Kreem job that looked anywhere that nice.

No problems guys n gals, for all that I have learned so far and the info I plan to wring out of this forum later it is the least I can do.
Dry time will be finished on Monday, hoping to have the carbs done by then so I can get the bike going, yea for soon to be first timer carb tuning fun  :o

I really have been trying to take a fair amount of pictures of what I have done so far so if the need arises for some pics of a 76 550K:
- Tank
- Petcock
- Carbs
- Soon to be other parts

Let me know
