My tank paint jobs starting to blister :(

Right so as you know when i got the bike over a year ago now the tank wasnt at the best state... It was crazy paving all the way... So i had to strip the tank and repainted it... Apart from some dripping lacquer on the kawasaki decal it actually went pretty well and to plan...


Untill now.

Why has this happened?

So yes some nights i leave the bike out here... It has been in frost.... this has been because I sometimes leave the house at 6:30 in the morning to get to town, so I didnt want to go through all the faff of going out to the shed (bit of a walk in the dark) set up a plank of wood as a ramp and then push the bike up it... Normally during the day its not a big issue but at freezing cold night its a pain in the arse....

So i figure, cars bikes and paint is designed to be outside... So I leave it outside some nights.

I was lazy this xmas I admit I should have put it away... but I didnt so its been out for a few days. And I just checked on the bike and found the blistering... Whats really perplexing is the weather. Apart from being misty hasnt been that bad. Its been a relatively warm Christmas here.

So whats caused this? Is it rust? (i suspect so because some of the line patterns suggest some kind of rust formed in a sanding line)

And if rust, how has moisture got through lacquer and paint? (I admit this is rattle can stuff)

Or also very likely... Did i do something wrong pre painting, should I have applied some kind of extra treatment?

I did do acid washes before to remove the few specs of rust that were on the tank when i stripped it, was there another treatment I should have done to seal it?

Well i cant repaint it as its too cold a time of year... And come spring I might be getting a new bike.

I might end up keeping the er6f to turn into a project bike but I dont know yet...

It was under a tree, could tree sap cause this?

Let me know your thoughts...

It's a problem from when you painted it. My best guess is that you didn't let it dry enough before putting the next coat on, but I'm not a painter, so I'm probably wrong.

[BTTD]

Have you spilt petrol on it? Rattle can stuff is not as resistant as 2 pack or decent cellulose.
I've used rattle can lacquer before and had it craze, yellow and flake off after a few years.

im still not convinced its petrol damage... the trouble looks like its under the paint... Some of the blisters form a line and such...

Anyway if im going to be repainting it I can do it properly now. We have the right guns for it.
Just has to wait for warmer times

Am I correct in thinking you stripped it all back to metal and then used an acid wash?

If so what steps did you take between acid wash and colour coat?

That doesn't look like lacquer breach issue, damp would make it bloom (cloudy) and fuel blistering would make itself evident by, usually, starting at the filler neck and spreading continuously rather than in spit spots all over.

My guess would be that tank was wiped with a rag that might have had some damp in it prior to colour coat or you sprayed it in a high humidity environment.

Is a cheap bike, I'd not worry too much.

Don't know what year it is but a clean non dented tank for 09-11 is 60 quid on eBay.

You've got damp in the paint and/or lacquer or not allowed long enough to flash off between coats, if you redo it, do it in heat of summer if you don't have any kind of heat source and preferably use a 2k base coat and lacquer, it will last longer.

[duhawkz]

I'd be wary of spraying 2k at home in your garage, unless you've got no neighbours and a airfed mask. Its pretty nasty stuff.

In b4. I've alway spray 2 pac naked without mask and I've not died yet

water damp under the paint ..froze expanded lifted paint ..

Don’t spray 2k at home, it can ruin your health instantly. Just buy a better tank or ignore the problem as it’s an ER6 and no one cares.

Hi,did you spray it when there high humidity in the air? I.e cold,damp outside but warm where you sprayed it?If so,when you open the door of your shed,area where you did it,cold air can come in and cause a very slight fogging issue in the air,condensation. You may not see it,but it can happen,causing minuscule droplets. This may have happen, but I can't say for certain. What's the inside of the tank like,also?

Maybe some incompatibility caused by the acid wash,especially if filler or polyester filler/primer was used...

Those lines indicate something probably contaminated the wet/dry you used.

If it were mine, it would be going back to bare metal & starting over with epoxy primer.
