How to make a grown man cry

[hjfisk]

While going over the Roadkill bike for our ride to Colebrook tomorrow
I noticed this on the newly painted tank;

[08rangerdan]

Who painted it? Hopefully not you lol

Looks like I'm riding the 1000g again

Thats gas leaking through

Thats gas leaking through

Ooh, that's a different story. It looked like maybe it had been painted with fuel-soluble paint (rattlecan, ie) that met fuel. Wow, that's a shame. So there's a hole in the tank. That's just awful.

[farmall]

Did you seal the inside of the tank prior to paint?

[bigskybldr]

That's hard to look at, I know how much work goes into a paint job.

[sedelen]

Don't feel alone, when I had my '79 GS1000E tank repainted, I didn't have it sealed. Why should I? It didn't leak.
That area under the gas cap, the recessed area was somewhat rusty, and it and the tank were all stripped, sanded and professionally painted.
Oh so beautiful it came out. But then these little "bubbles" started appearing on the paint in that recessed area. Seems there was enough rust that it developed pin holes, although not visible, allowed air to escape under pressure resulting in those bubbles.
I had the guy completely re work it, but we both under the impression it was a leaky gas cap seal that caused it. The result, it developed those bubbles again.
Now, I wished I had sealed it in the first place, but oh well. I didn't have it fixed again and the paint has since lifted and cracked. But you don't see the damage until you take the gas cap off, so I live with it.


I've often wondered what I should do about it, and then never did anything, but if it really gets to bother me, I'll just grab my other tank out of the closet that was also repainted, and was sealed and put it on it.



Those are not decals either, those were painted on there, no ridges. Should've had that tank sealed.

That really sucks, but as Sedelan says don't despair, same thing happened to mine except mine was caused by a bad spot weld at the front where the locating lugs slide onto the rubbers. I silver soldered all around the lug all the time blowing compressed air through the tank to minimise spoiling the paintwork. I put a little pressure and used soapy water as a test to check it was sealed. I sent the tank back to the fella who originally did the paint work and he did a small repair job. You would never know it had had a repair.
Personally I don't like the idea of coating the inside of the tank, the place where yours is leaking would be an easy braze repair and just wash it along as far as you think would be necessary, a repair paint job and call it job done.
Don't panic, it really isn't as bad as it first seems.

That sucks Harry. Well its gonna need redone, so its time to do a tank liner.

[hjfisk]

I didn't line the tank because it does not show any rust on the inside. It looked like new. The rust was on the exterior. Just surface rust we thought. I didn't paint the bike. I had my brother do it. He is not a professional just a dabbler, but does a pretty nice job. So all I am out is, disappointment, materials, and time. I have not used a tank liner before. I picked up a POR15 liner kit, can anyone recommend, or condemn this product for me?

[tkent02]

POR 15 is highly recommended, follow the directions exactly.

[sedelen]

I think Por 15 is the one most of us go for.
I used Kreme once on my Skunk back in the day, it didn't work, and I threw that '78 GS1000E tank out with the trash, but that was in '83 (I think) and you could get a brand new painted tank for $200, and I did just that.

[chuck hahn]

I use and suggest the Caswell kit.

[850 Combat]

The only product I have ever used is Kreem. on my 1968 Royal Enfield 750 TT Interceptor. I put it in in 1987, without too strict adherence to the instructions. When I sold the bike in about 2002, it was still holding up fine, with no problems what so ever. Many people have had a different experience. I suspect that you might find that with many of these products.

Never should have sold it.
