spraying interior trim

[euromandeluxe]

hey guys,

i've got this blue woodgrain trim in the car that i hate, and i reckon i'm gonna try to spray a metallic silver finish over it. i bought this aerosol spray can from bunnings in the finish i want which is apparently alright for spraying straight onto plastic.

initially i tried taping some silver roll on stuff from autobarn but theres too many tiny air bubbles which are obvious, and two direction curves are a bitch.

anything i should know before i spray the plastic? any tips?

thank guyzZ :thumbsup:

dont know how well it would work, but you shuold be cleaning it with perhaps some metholated spirits and since its on the interior you shouldnt need to sand or anything of that nature, just give it a clean, prime, and spray
and pics when ur done
2-3 coats of primer,
2-3 light coats of the stuff you've got

why wouldnt primer be needed ?
there are plastic primers out there in addition to metel ones,obviously im refering to plastic

I see. i've only done one piece so far - a piece i don't really need in case i f*ck it up.

I thought i'd give them a sanding with some wet/dry sandpaper - around 600 grit. didn't seem rough enough so i tried 360. it wasn't that rough with 360 either but it looked pretty scratched up so i stuck with it.

i skipped priming. hopefully i don't get any peeling in the next few weeks. though i did call around a few places for plastic primer, and the only ones i could find were the ones suited more for bumpers etc, which aren't glossy like the fake woodgrain stuff.

as far as protecting the finish goes, would normal clearcoat that can be used on exterior panels be okay?

The reason there is primer available is because they make money selling the stuff to beginners.



lol....

Primer is NOT needed if the surface to be painted is plastic and has been sanded there is no reason to use it. The reason there is primer available is because they make money selling the stuff to beginners.

A clear coat will work but it will be shiny not satin finished.

I see.

so, to get a more matte/satin finish, what sort of topcoat do i use to protect the paint? i'm pretty sure it'll chip if there's nothing on the top.

OP if you use the right paint you won't need primer I used vinyl & plastic paint on the interior of my last car and it lasted near 7 years until the car was crashed

You couldn't even scratch it off

Just make sure you do as claymore said and scuff it up first I used a scotchbrite. I also used prepsol to make sure I removed all the silicon based products that may have been used on it.

[ek4-guy]

It's called plastic paint because it's designed to be sprayed on plastic not on primer

You use plastic primer when you are spraying normal paint on plastic

I paint machine parts nearly everyday at work ;)

awesome, so i don't need any primer to make the paint stick. thanks heaps :) :thumbsup:

i'm using Rust-oleum universal all surface paint, which is supposed to be alright for plastic. i've tried it on one piece of trim and it sticks pretty well.

however, i still need to know what to use to protect the basecoat (a top coat of sorts) whilst still obtaining a satin finish. i don't want super glossy reflective silver pieces all over my car's interior! haha

is there 'matte' clearcoat available from anywhere?

thanks in advance :thumbsup:

i beleive general plastic clear coat is fine,
most/all aerosole clear coats dont ever come up super shiney glossy anyway because its acrylic

tiksie should be able to shed light on this topic i beleive?

I've started painting my marble woodgrain trim too. It's ugleh! lol!

I wet sanded mine down with 800 then 1200. I used 3 coats of plastic primer, then wet sanded that with 1200. Painted 3-4 coats of colour, 4-5 coats of clear, wet sanded the clear with 1200, then a final heavy coat. It turned out very good (gloss not matt)

At the end of all that, I didn't like the colour (gunmetal which had a greenish tinge) so I'm going to redo it LOL. It was only one panel, so not too much time lost. I'm going to do metallic black next.

I'd also like to know how to get a matt finish if someone can shed some light. I thought of using thin coats of clear, or just wet sanding it with 1200 or higher.

Great, thanks guys!

dtngo, what brand plastic primer did you use, and where'd you get it from? just the standard K&K plastic primer autobarn sells, or is there something better?

[dtngo]

Same. Just the K&H stuff.
