How to (or how not to in my case) paint an aluminimum bike frame

[Tom]

Hi all,

I thought Id ask if anyone has ever tried to paint their frame on their
bike? I have actually attempted this, but it seems the method I have used
has not worked very well..

I rubbed down the frame to the metal, using wet and dry and then painted the
frame using an aluminium etch primer. Once this was dry a few coats of
cellulose paint went on to finish.

I was very happy to see (note sarcasm) that all the paint started to crack,
and since the frame has been hanging in the garage it certainly wasn't due
to wear. Perhaps the paint has reacted with the primer?

I did ask the store for advice and this is what they gave me (I wont be
going back to them). I'm not really wanting an A-Grade finish since it will
be all messed up in a few months time, but it would be nice to get a
reasonable job done.

Ill get some pictures of the paintwork up for anyone who might know what
could be the problem on a website tomorrow, and if anyone has any info on
this Id appreciate the details.

Thanks,
Tom

Hi Mark

There are a few places I know that take bike frames for re-sprays but I'm a
gluten for punishment :) I am in the UK but thanks for the link.

Cheers,
Tom

Then perhaps you should check out: http://www.gluten.net/welcome.asp

..... sorry, a bit OT, but it just struck me as funny.

From my experience, it was the cellulose thinners re-softening the primer,
which must not have been a compatible one. You need a cellulose paint primer
under a cellulose top-coat to stop this happening in future. I'd go back to
the store and shoot the dumb arsed ****ers dead, before making them re-paint
your frame for you.

After I have built my bike I might learn to spell (and not rely on spell
checker)

haha I like your humour :)

Thanks very much for the info.....

Ive had the nightmare job of flatting it back to remove the cracks, and Ive
dusted it with a few coats. Im hoping I can just keep spraying, and then
rubbing it down to get a good finish.

I think it will work well but Im not very happy about what they told me.

I use Aluminium etch primer, and then cellulose on top. Im assuming what
you said would require me using the aluminium etch primer and then using a
cellulose primer on top of that?

Cheers,
Tom
