Thanks Derek (and Sacha and Mike) for some good suggestions and tips.
I'll have lovely spray plastikoted glossy black wee tables (probably
cast alu) by the end of the week end :-)

Cast alu needs a different primer.

Even with Hammerite????

They must have some reason for selling this

"Special Metals Primer

Hammerite Special Metals Primer promotes adhesion of Hammerite Metal
PaintT on
non-rusting metal surfaces such as aluminum, galvanized and stainless
steel,
chrome, brass and copper. Quick and easy to use. Only 1 coat required.
Touch dry
in 1 hour. Topcoat can be applied after 1-2 hours."

The important word here, is "PRIMER", i.e., for use on bare metal. These are
usually done with an 'etch' primer where the paint actually eats into the
metal and acts as a key for the next coat. These tables have already been
painted and it must be assumed, 'assumed' note, that they have had their
etch primer on. However, "IF" the paint starts peeling off back to bare
metal, then the etch primer is NOT on there and for a proper job, the whole
thing will need to be sand blasted or dipped back to bare metal and start
again.

I EXPECT, that they have been done and therefore a quick rub down and spray
should be satisfactory

Hope that helps.
