Hi all,

Right, I've got the splitter from that 'yay or nay' thread aaaages ago, and I haven't fitted it yet, however I plan to tomorrow.


I also bought a can of Trophy Blue paint in an aerosol a little while back to paint it.

Now, this splitter is made from plastic, can I spray straight onto the splitter? or do I need to primer it first?

Thanks all,
Jake

You wouldn't want to sand it after you have painted it unless you have made a complete hash of it and need to start over. You shouldn't have to sand inbetween layers of laquer either I wouldn't have thought.

I'm just going on what I see happening in bodyshops, cans may require a slightly different method. I'm sure someone will correct me if the above is incorrect.
 
Well, be aware that many plastic primers are purely adhesion promoters, non-sanding. If you want a really good finish then you will definitely want to have the surface nice and flat before you put paint on. In which case you might want to use a high build primer after the plastic primer, sand this with a 600 wet paper using a block (block is essential, guide coat will help you a lot at this stage, google it). Then degrease with panel wipe or thinner (2 cloths, one on, one off), dust off with a tack rag, then spray 2 or 3 coats of your colour 5-10 mins apart, don't sand this, then your clear lacquer. You can then sand it after if you like to knock out orange peel, dust nibs and so on. For this use 1200/1500/2000 wet papers in that order, i'd give it a couple of weeks before doing that though, and you're gonna need a machine polisher or arms like popeye to buff the scratches out.
 
Make sure you leave it to dry for a LONG (a good 24hours after painting and laquer) time ...Dont be over eager to go onto the next step or you'll ruin what you've done and have to start all over...
 
Also, when spraying from a rattle-can, stick it in some warm (not hot!) water for a while before you use it - this will make the paint flow out of the can MUCH better, and you'll find it both easier to spray, and you'll get a better finish as the paint will come out thinner :)
 
You need to use plastic primer. rub down after its cured. then normall prime rub again. any break trus spot prime rub those areas and one final coat of primer.

Now if your prep is right you dont actually need to flat between coats or paint.
Now as that blue is quite a dark one lay down 5 coats in total.

Of course if you get any runs or orange peel your going to have to flat them out.

after thats done slap a few coats of clear on it and wet sand them. make sure the surface is well lubed up useing fairy liquid and water for instance.

As long as it's not metallic it's perfectly ok to flat down colour coats.

That's not true, I won't go into the details, but his car is almost certainly metallic anyway so barring all the problems it causes with the chemical reactions, it will kill the metal flake effect totally dead.
