I used a Citrus cleaner I picked up at one of the big box home stores.  Hand painted with Testors enamel, good adhesion but did not care for the brush application.

Hello All,

da1
For complete clarity I admit to absolute ZERO previous success with resin parts.

A manufacturer of aftermarket resin shells says...

"Highly recommend cleaning shell before painting with either mineral spirits or lacquer thinner. Use a pan to soak for a short period of time use a small brush or tooth brush (SIC) to brush off inside and outside of (the) shell/part. Just wipe with a towel and let air dry. Do not use a(n) air hose."

***Use nitrile gloves and eye protection while using solvents and dispose of used chemicals properly***

When I painted one of these shells I hadn't read his prep instructions and washed the shell in warm soapy water with Dawn® dish soap and allowed to air-dry.

I used Rust-Oleum® Painters Touch 2X Gloss Black.

This rattle can paint touts it "Bonds To Plastic!"

I used the bain-marie method to warm the can and did several light passes.

Despite this paint being a "Paint+Primer" the fine details of the grills and doors on this shell are still visible.

Hope this helps.

"Uhh...I didn’t know it was 'impossible' I just made it work...sorry"

I have done a few Sylvan kits aS well as other resin kits. Keep in mind that many resin kits have small, delicate parts that are fragile. A light touch is needed for cleaning

I have assembled and painted a few Sylvan kits.  All I used was Ivory dishwashing soap & warm water, a soft toothbrush (for gently scrubbing the surfaces), a warm water rinse, and allow it to thoroughly air dry.  The key is to remove all of the releasing agent from the surface of the resin.  Otherwise, the primer/paint will not adhere well.

I have never built a Sylvan kit, but I have built dozens of resin freight car kits and hundreds of resin gaming miniatures.

There are two concerns I have with prepping these parts.

1) All mold release must be removed and parts must be clean.

2) There must be a "tooth" on the surface for paint to stick to.

For #1, I am sure Zep cleaner will work, so will Dawn, Windex, Ivory Snow, and probably hundreds of other products. I have used all kinds of cleaners and all have worked.

For #2, Not all models require this. Most castings are a little rough, but some are as smooth and shiny as glass, and paint just will not stick to these. If a part is slick and smooth I use CRC Brake And Parts Cleaner on it. This will slightly dissolve the surface, then I dry it quickly with compressed air and let it dry thoroughly.

I love resin kits; This one was a blast!

I built (well, I'm half-way there, anyway) the Sylvan Great Lakes Ore boat and I found that a prep cleaning using Simple Green cleaner worked very well to remove the mold release prior to gluing and painting.

YMMV, Cheers, Ed

Thanks Tom I did a forum search and it was not on the first page.  It could have been on the 2nd or 20th.

Henry,

I believe this is the link that Dwayne was trying to post:

http://cs.trains.com/mrr/f/88/t/251079.aspx

I copied the words in the 2nd post and pasted it in a Google search...

Dwayne,

The last time I painted one I used Pollyscale from a jar and a brush.  If I were to do it again I probably would use a rattle can, since I do not presently own an airbrush.  I'm a big fan of Tamiya spraypaint because it goes on thin & evenly and I've never experienced a clogged nozzle.  The thinner paint is also less likely to cover over finer details.

Ack!!!  The thread I was referring to is here: Preparation for polyurethane resin kit - Model Railroader Magazine - Model Railroading, Model Trains, Reviews, Track Plans, and Forums 

Do you have a better link than that?

Prep for Sylvan Scale model
Posted by da1 on Sunday, November 29, 2020 7:04 PM

Hello all.

About to attemp a Sylvan Scale Models vehicle kit and found this thread.

For complete clarity I admit to absolute ZERO previous success with resin parts.  That is based on attempts to paint the windows, doors and foundations in Kanamodel kits.

So, I see that Zep Citrus cleaner is recommended.  Can one of you with experience provide simple step-by-step instructions for using Zep and/or water and/or dish soap to prep these parts for acryllic painting?  Do I scrub the parts with a toothbrush?  Do I rinse with a water and a toothbrush?  Knowing the parts are small and delicate, is Rustoleum rattle-can priming advised?  Should I stick to brush painting, or will accrylic airbrush be okay?

Again, pretend I am a total novice when replying.

Thanks in advance.
Dwayne A
