    strange, if you've rubbed it down you would have taken anything of the surface that may have been on it..........

    could be soomething as simple as not shaking the primer enough?

    spraying it a little too close..

    hope u sort it mate

    no mate, didn't think it would, even if it did, if you rub it down again it would take it back off. Which primer you using? Did you give it 3/4 coats?

    The bubbling is caused by solvent from the paint getting under the very thin rubberised coating on the main console. Sanding it down a little too much causes small perforations in the coating which allows the solvent to get underneath - ergo it bubbles and lifts.

    The only way around it it to sand it back flat and them build the layers of paint up again using very very thin coats - just a dusting each time really. Standing the can in hot water before you spray will also help as the heat will make the solvent evaporate more quickly on contact, before it gets chance to creep round the back

    thats a good tip Geoff, about the can in hot water.

    I only found out the hard wat after suffering dash bubbling syndrome.

    I only "discovered" the rubberised coating whilst trying to remove the glue from some Irmy heater rings with cellulose thinners..

    The hot water trick is great - especially on the lacquer coat as it thins it out no end and helps to get a flatter surface for polishing. However as it s thinner it is prone to running - so it's a bit of swings and roundabouts. But it you do it right it's all swings and no roundabouts
