Title: stripping paint from a kato
Post by: tom mann on January 08, 2007, 03:37:55 PM
There is always a lot of discussion about this, but will just plain 91% alcohol work?

I suppose it will take as much time waiting for a reply as it would take to dunk it and see...

Well, it seems like it could take forever, don't know if I should continue or do something else.

I used 91% to strip some Kato caboose bodies with no problems.  I used it in a ultrasonic cleaner.  The shells came out okay but the alcohol was not too kind on whatever type of clear plastic they use in the lid of the ultrasonic cleaner.

Cool thread!  I have a few Kato PAs to strip this weekend.  I was going to try ELO, but I'll give the isopropyl a shot first...

This comes up from time to time. People who have done it say it is the best for Kato paints. Some colors, however, just don't come off completely. Frank

I have had very little luck stripping paint from Kato locos. I suspect that a blow torch would work as well as anything ::) ;D . I have been advised to just paint over the original.

I used alcohol to strip 4 Kato F3's. Worked just fine.

You might have to be careful with ELO since in can make some plastic brittle. I use alcohol and Badgers sandblaster for best results. The sandblaster even removes the paint in the radiator grooves.

91% alcohol and a round brush in a flex on a dremel with low rpm will work ! *
(and if you try to strip a new run Kato Conrail SD40 be prepared to strip them twice - yes, they are painted and pad printed twice !)



* that's how I strip Kato shells...

Whatever you do, DO NOT GO NEAR A KATO SHELL WITH ELO- IT WILL CRUMBLE INTO PIECES!!! :o I lost two SD40 shells trying to strip with ELO not too long ago. As soon as I started to scrub with a toothbrush, they literally came apart in my hands. I have used it on both Atlas and Lifelike shells before with no problem, so I guess Kato uses a different type of plastic for their shell that doesn't react well to the ELO.

Thanks, guys.  Isopropyl it is!

If it's a single colour KATO I'm working with I don't bother stripping the paint.I will use Acetone (fingernail polish remover for those that don't know) and just remove the lettering then spray the new colour and decal to suite.

I have 5 Kato SD40s + 2 SD45 + 2 U30C (olde).  They still had remanents or more of paint from previous attempts.  I soaked them in 91% isopropyl.  A toothbrush got off the paint off the shells along with a bicarbonate sandblast (99.44%).

There was some slight residue, no prob.  I was happy.

I soaked the sills and handrails, left them immersed for a week.  Not good...  the delrin/whatever engineering plastic of the handrails absorbed the alky.   The curve of the assembly was impressive... NOT. 

Luckily, after toothbrushing (might just as well) and letting them sit for a week, the handrails shrunk to their original size. I was happy again.

Moral of the tale:  even benign(??) solvents might not be...

My mileage (your's may vary):  91% isopropyl or denatured ethanol is the first step.  I have Chameleon: $7 for 8oz, alky is about $1 per quart.  ELO on a q-tip removed some old Atlas(Roco?) paint that 91% didnt touch (neither did oven cleaner).

I will not use brake fluid. Period.  I'm not thrilled with PineSol either.

Be cautious.

I have two Kato F3 sets to be repainted. I'll give the 91% one more try. It may be that different colors act differently. My Chicago NW SD-45 was impossible to strip. My F3's are the Burlington Northern. Maybe 91% iso will work better on deep green.

I use the stuff I get from NAPA stores, it comes in a purple bottle, its sold as a degreasing cleaner. Works best on that very stubborn red Kato paint. Had no luck with Chameleon nor 91% alcohol with the red but the cleaner worked pretty well.

Probably about the same as the BN passenger cars... the white will come off really easily with alcohol.  The green will take longer.  I just started removing the white lettering and stripes, and painting over the green.
