    Thought Id save money and spray paint my newly purchased e46 mtech sport bumper (hard pastic) using hyco spray paints - talk about learning the expensive way

    The paint, titan silver, started to drip, I panicked and try to smooth it out using 1200 grit paper from halfords and resprayed - it looks awful!!

    What grade of sand paper do i need to take the paint off and start again -600?

    Don't really want to take to a body shop yet, they'll laugh at me

    The bottom half came out quite well so based on this I'm giving it another go...

    Any advice.....

    the key to home spraying is take it slow and build it up with layers. too much paint and it will drip. Always allow each layer an hour to dry before applying the next one.

    don't leave for an hour..read what it says on the can....If you leave it for an hour the paint can all bubble up and look really sh*t........

    600 should be fine,what you want to do is have several types of sand paper and start with the roughest working your way up to the finest.Then makes sure you properly degrease it all or the new paint wont stick to where you have left finger prints etc....

    Will I need to take off all the paint? Only the bad bits?

    What can I degrease it with?

    flatten back the bad bits and make sure the rest of the bumper has a key so that the paint can adhere properly.. you don't need to take it all the way back as you'll effectively just be blowing over the good bits (but the paint still needs a surface to stick to - hence why it needs a key).

    If you have high spots in the paint use a block to work them out gently, degrease, prime and as said spray light coats and leave to dry.

    Most people think paints dry and it really isnt! Youtube is full of HOW TO PAINT A CAR BUMPER

    Watch some videos and get the general idea. I always find it easier when ive seen it done! hope you get it sorted chap.....

    I forgot to say that if you're using rattle cans it would be an idea to get a gun adaptor for the aerosol.. PlastiKote do one on ebay for about £3 or £4.. it'll give you a bit more control when spraying..

    Hope you haven't bought your titan silver rattle cans from Halfords. One of the worst colour matches you can get.

    true!!

    I would never use Halfords paints.. I would however recommend: www.paints4u.com
