correct me if im wrong ppl, but u need to key the surface, then a few coats of primer, with a lite sand down in between then a few coats of colour, then lacquar

you'll only get a perfect finish from a bodyshop but since theyre small bits then have a look at the how-to for colour coding the bump strips...same process

[Ffoeg]

You'll easily get a perfect finish if you take your time and do it carefully - and refer to the How To as mentioned above

[dr_shabzzz]

the main problem i have at home is dust...no matter what i do dust settles between layers making the finish uneven

garage or shed???

i would think doing it yourself would invole 25 pounds worth of materials and then time - id pay the extra 50 to have peace of mind it wont orange peel, paint/laquer run, crack or have the paint not stick properly.

the local garages are charging £70 - £100 for spraying two little bits of plastic.Just read that bit

Tell them to bollocks - that's way too much for those.

Shop around and you'll defo get much cheaper than that

its was only £50 to spray and fit my spoiler

firstly key the surface with 800 grit wet n dry paper.

then give it a good clean with pannel wipe or if you dont have that use some meths

then give it a ipe over with a tack cloth (cost about £ for 3 from halfords)

then build up several light layers of plastic primer, allow a 15-20min flash time betwwen coats

leave for atleast 24 hours then flat back with 1200 grit wet n dry

give it a good clean again with panel wipe

then build up a minimum of 5 coats of top coat, again allowing a 20 min flash over, build it up ligh and even.

for best results if using a spray can is to put the can in hot water for about 5-10 mins just to atomise the paint better, then turn the can upside down and depress the nozzel until nothing comes out, this way makes sure the nozzel is clear,

press the nozzel about 6 inches away from the end of pannel and do nice even passes and let off again about 6 inches after, also make sure ht ecan is at 90deg and bout 30cm high off the pannel

over lap each coat by about1-2 inches

once your happy with the amout of top coat leave for about 24 hours again

if the finishis a tad orange peel ( looks like orange skin, dipples in it etc) then give a very light colour sand with 1500 grit wet and dry,

then another a good clean with pannel wipe and a tack cloth

the build around 7 coats of clear lacquer leaving a 15-20min flash time between coats

once happy leave for about 24 hours thats nice and warm

if again your not 100% happy with the finsih lightly flat back with 1500 give it a clean an give a few more coats of clear lacquer

If you know your stuff leave it for a few weeks for every thing to harded properly flat back with 1500 and buff to a high shine with some cutting paste

note that you shold only do this if your confident as it could make a pigs ear of the whole job and cost you a full repaint on them again

main factors are not to rush and keep it free from dust at all times

hope this helps

7 coats of lacquer? In my experience that will quite easily get "clouding".
I personally prefer less but thicker coats of lacquer.

By the way, wet the floor to minimise dust (unless you are painting in the front room or kitchen!), and wear a mask.

the "clouding" that your on about is "blooming" its when moister gets in the paint or lacquer and leaves a light milky layer on the top

main way to avoid this is to only do it a draught free area

or you can use anti bloom lacquer but thats only any good if your using a spray gun and takes alot longer to dry if your not using an oven/booth

7 coats isnt excessive, aloows for any mistakes to be rectified hence why i said if your not happy flat back with 1500 to polish it up

im a traied sprayer and these are just a few little tips that you learn on the way:wink:

And some good tips indeed :)

But seeing as you are a trained spray, I have another question if you don't mind :D
I have sprayed a lot of parts in the past, but they are all easily stone-chipped, unlike the manufacturers' original paint. Is there any special primer or special coating that can minimise stone-chipping?

(I am a trained sprayed too, but unfortunately not in automotive.)

have you painted these with spray cans at all? or with a spray gun in your home or shed/garage?

trouble i find painting things at home in the shed or garage etc is that the paint dries at room temperature where as if its done a spray booth with an oven you bake the paint and it makes it harder.

or option 2 which is dangerous unless youve gott eh correct equipment and a proper spray booth to do it in is

whats called 2pack paints or 2k acrlyics

these paints contains some very nasty chemicals an compounds such as cyonide (sp)

these paints harden with a chemical reaction and dry nice and hard where as std paints that you get in a can or safe to spray at home are either 1 pack acrlyic or celouse, these dry with a atmospheric reaction (air dry) but dont dry as hard as 2 pack unless baked in an oven.

as stated though 2 pack should only be painted in a proper booth and YOU must wear an air fed maskor its a trip to hospital within a few minutes of painting with these.

hope this helps
