That Chrysler looks great, but I am gun shy about using Tamiya without primer. I have not found anything that will strip Tamiya if the paintjob goes south and there is no primer underneath to soften.

90%+ ipa will take it off fast. just use a cloth and a couple of cotton buds. it can leave staining on the plastic from reds and blacks sometimes. Its pretty much all i use for stripping now

Not for me. I have an interior bucket that I soaked in various things for years and it barely made a dent.

It works for me on everything except matt black and silver  paint. I soak it until it gets slightly sticky then start rubbing with the cloth and cotton buds and it soon comes off. I did find it poor with duplicolour kawasaki green, it took a lot of careful scraping with box cutter blades

Tamiya makes a special paint remover similar to the old Testors “Easy Lift Off”:

You brush it on, leave it to work for 5-10 minutes, brush to release the dissolved paint, wipe off with a paper towel, and repeat if necessary. Once all of the paint is gone and the paint remover been thoroughly wiped off, you clean the model with dishwashing detergent and rinse off with water.
It even removes some of the most stubborn other types of paint, that brake fluid and lye-based degreasers/cleaning products can’t.

Yes mate, mentioned else where in one of the other threads. It is pricey, but worth it, when you wont have to sand.

 

Also when using spray cans in winter, place the can in some hot tap water for 5 min before shaking and spraying. It will help the paint atomize better and get a smoother finish.

Mate I've got the Tamiya fine SP   coming hopefully early this week. Do I need to remove all that undercoat before I spray it with the Tamiya. Thanks Don

I would strongly recommend stripping the previous primer to avoid excessively thick layer buildup and prevent possible paint compatibility issues.

 There are also many gifted model builders out there who have never watched a video or visited a forum. They learn by….experience.

My guess would be that almost all of us who've been building relatively continuously for the past 50 years or so, had to figure things out on our own.

That's not to say that I haven't pick up the occasional tip here and there on the forums or Facebook groups, but the vast majority of what I've learned during my modeling career came from either experimentation, or face to face interaction with other builders.

I don't put any weight at all into Youtube videos.

Just my opinion, but I think the majority of those guys that I've seen are better at producing videos than they are at building models.

But then again, I don't watch many, so.........

I have parts like that too.

A flat black interior from a '65 Olds 88 that I tried soaking in among other things, IPA.

No affect whatsoever.

Thanks Chris, Primer hasn't arrived yet, so I'll use the time to do that and let it dry. I'm still learning, (again), hadn't thought about the layer build up. Thanks for your help.
