Painting Plastics Universal Guide
This guide is meant to help all of you who wish to paint some
part of their car, or anything else for that matter, that is
plastics. This could be your dash, engine plastics, OEM side
skirt ECT. For demonstrational purposes I am going to use the
stock dome light to show how to prep and paint plastic pieces.
ē Medium Sand Paper (only if its already a smooth finish such as
ē Fine Sand Paper (I used 100 grit I think but I would get finer
if you can)
ē Simple Green Soap (Gets off all grease and oils. Esp. good for
dirty engine plastics)
ē Plastic Primer (Many plastics dent to chip when painted. This
ē Paint (This is up to you. You do not need High Temp Duplicolor.
Any regular spray-paint will work if your going to clear coat.
If not clear coating I would get Duplicolor.)
ē Clear Coat (I just used some America Tradition clear coat from
Lows. Its cheap and works great)
ē Tee-shirt (Great for wiping down the part between coats.)
ē Blue painters tape (if needed)
Tip for spray painting: Always do a few light coats over 1 thick
coat. I normally do about 3-5 depending on how I like the color.
More coats the darker it gets. Also when you paint, I highly
suggest you hang up the part at an easy to spray level. You will
get a much more even coat then if itís on the ground. Finally,
when actually painting, never start spraying on the part. Start
at the top edge about an inch or so staying good 6 or so inches
in front of the part. When you spray go past the piece on each
swipe and move back and forth in a zigzag pattern. You do not
need to get it completely covered the first coat. For more tips
feel free to ask me.
1. Clean the Part: I suggest using Simple Green. It works great
on getting grease and oils off. Itís a must when doing engine
plastics. Let dry for 5-10 min.
2. Prep the surface: If itís a smooth finish already like the
center console use some medium sand paper and scuff up the
surface a bit. Not big gouges but make it a bit more ruff. I
didnít do this for engine plastics and it seemed to be fine.
Also if you need to cover up any areas I suggest using the blue
painters tape. If you get the thin kind you can do precision
areas. I just used the standard kind.
3. Primer: As stated above do light coats. For primer you do not
need it thick, I would suggest 2 coats maybe 3 depending on how
big the piece is and how light the coats are. Let sit for about
15 min between coats depending on humidity. Itís really humid in
Florida so take a bit for it to completely dry. NOTE: After
using primer I would suggest waiting a few hours before
commencing with actual paint. I waited a day before just to be
safe for the engine plastics due to the great heat that it has
to deal with. For this project I waited a few hours.
4. Paint: Now that the primer is on, make sure you dust off the
piece; I used a damp tee-shirt. If you do this let it dry then
begin painting. I suggest painting as noted above. Wait 15 or so
min between coats. I did about 5 coats on the engine plastics
and about 3 coats on the dome light. Itís all up to you on how
you like the color. Use the fine sand paper between coats to
smooth down any ruff areas. But I would not suggest sanding
after the last coat. NOTE: If you are clear coating then the
piece does not have to be shinny and smooth, the clear makes it
smoother. NOTE2: If you are clear coating it is recommended to
wait 24 hours after doing your last coat of paint. The clear
supposable will melt and eat away the paint if you do it sooner.
I always let it sit 24 hours so donít know otherwise.
3rd final coat
5. Clear coating: I highly recommend clear coating your paint.
It makes it easier to clean the paint if dirty, give youíre the
nice glossy smoother look, brings out the color more, in my case
it make the blue darker, and finally if you not so good at
painting it covers up most of the uneven painting you may do
Clear coat works just like paint. I normally do about 3-4 coats
of clear. Wait about 15 min between painting as before.
6. CAUTION: When working with engine plastics, clear coat or
not, you must wait at least 24 hours before putting them in your
car and driving. If you do so earlier you run the chance of the
paint bubbling or chipping off. I let mine sit a weekend before
driving to be safe.
7. NOTE: I suggest wiping down your engine plastics after rain
because they are easily stained by dirt and water esp. if not

that matter. For metal just get a metal primer and have at it
