2nd Gen Interior Trim Painting Help!

[Grant McBay]

Hi, I’ve been having trouble trying to get good coats of paint down on the interior trim on my 2nd gen Tacoma.

I have tried many combinations, but nothing seems to give me good results. :/

First attempt:
1.) Use TSP to clean off grease or stuck on seal from the factory paint
2.) apply 2-3 coats of adhesive promoter
3.) Let dry
4.) paint 3-4 coats of duplicolor viynl & fabric paint
5.) apply clear coat krylon protective spray

Result: surface feels rough, paint comes off easily with just a little rubbing alcohol or water and a rag.


Second Attempt:
1.) Sand all surfaces with 600 grit sandpaper
2.) apply TSP like in first attempt
3.) dry with microfiber cloth
4.) apply 2-3 coatsuniversal bonding krylon white primer
5.) dry primer
6.) apply 1-2 coats adhesive promoter
7.) apply duplicolor vynl and fabric paint
8.) apply krylon clear coat again

Result: good color on the grey trim parts that come stock on the car. Good color in combination with the duplicolor especially if you use a white base; close to stock grey if not identical. Yet, it still wipes away pretty easy and has a rough texture. Paint doesn’t feel like sticking well. (Side note: cotton towels tend to leave behind a bit of fabric that clings on to the surface)


All in all: I need some specific technique in doing this. I’ve been working for 3 weeks trying to get this right so my truck’s interior paint isn’t crappy.

I’m trying to get close to factory feel and condition on my trim without having to buy brand new trim. If anyone can give me detailed instructions on how you’ve painted the interior trim on your own 2nd Gen Tacoma, please let me know! I’m just a 17 year old trying to make my truck look nice

Welcome to the forum.
Painting plastic is tough. You’ve got to use a lower grit sand paper. 600 grit is more for finish. Get 220 or even 120 grit
Your step 2 seems like you’re close.
I would only use one coat of the primer and the adhesive promoter. Maybe try all Krylon or all rustoleum products. Sometimes products are made to bond better with each other.
TSP is good to clean walls and wood before painting.
Rubbing alcohol works better for cleaning plastic.
Hope you figure it out.

Thank you so much for replying, I’ll try and get some pictures together by tomorrow as well as pictures of the products I’m using.

1. Sand with 220-120 grit
2. Clean with rubbing alcohol (let dry)
3. Apply primer 1 coat (let dry read can for dry times)
4. Apply adhesive promoter 1 coat (dry time on can)
5. Apply 1-2 coats of paint (dry each coat for time on can)
6. Apply clear coat 1 coat (dry time on can)

Won’t sanding it with a lower grit create more area for fibers from a cotton towel or something to stick on to it? Every time I try and wipe a “finished peice” the paint would start to streak off and/or tan prices of the cloth leaving blue fibers or whatever all over it

Get the cloth really wet with rubbing alcohol and let it air dry.

Also make sure you use light coats of primer and paint. I like to let each coat completely dry and then light sand between each coat. Sometimes heavy coats without drying or sanding in between won't cure properly and tend to stay soft/tacky.
