Paint strippers. What's your current favorite?

[ebinmaine 74,161]

What's your current favorite method of removing paint from metal? 

 

Chemical? 

 

Mechanical? 

 

My Workhorse is getting a repaint. The two year old maroon ish needs removal so I can get some gray on it...

 

What say you, fine Redsquare folk?

Two year old paint should strip easily with chemicals, I don’t like to use mechanical methods till it becomes necessary.  However paint stripping products aren’t as effective as in the good old days, I guess the safety police meddled in that.

Rustoleum make what they call Aircraft Remover. I've had a partial spray can on the shelf for many years. I ran across it a while back and thought I'd try it again figuring it wouldn't spray after all these years. It did. I forgot how nasty it is. Even the mist will feel like acid on your skin. Yup, first hand info. Give it a few minutes and the paint will basically drop off. It's still sold but, like lynnmor said, it's probably watered down now. I've tried about every stripper out there and haven't found anything close.

If your old paint is not peeling or flaking, I would not remove it. Wet sand it with 400grit and spray over it.

This particular case, some of it is scratched or broken already and I don't want to leave it there because the maroon has such a sharp contrast to the gray going over the top of it. It will get scratched again. And I don't want to see a two color scratch.

I'd rather just remove it now while it's easy.

Looks like @Blue Chips has pretty good results wrapping the stripper.

Was the original paint remover prior to the maroon paint?

Since it's newer paint I would expect some of the newer strippers like Citistrip to work OK. 

Wrapping tightly in thin plastic does help, it slows the evaporation so the product works on the paint longer.  

The "Aircraft Stripper does an excellent job, but it is pricy. 

Since it is newer paint, try wiping it with a very wet rag of lacquer thinner, it just might wrinkle right up.

I've had good results with CitriStrip gel on various items. As @oliver2-44 mentioned, wrapping the stripper in a poly sheet keeps the gel wet and working for a long time. Sometimes a second application is needed. You could buy a small bottle and test it on a small area to see how it works.

 

Results will vary with the type of paint. It seems to work well on 1K single-component paints, but 2K (two-component) paints are more chemical resistant.

This is single coat Rust-Oleum 2X. 

 

Sounds like it could work.

 One reason the finish on WH tractors and implements turns to that familiar rust-brown color is that they did not use a primer prior to painting & top coating. That makes for a rather thin base to build off of later...  it all depends on how chipped, flaking, or rusted the overall finish is to decide to strip it to bare metal or not. Unless you are a total hack & just use a paint brush or roller!

Agree, I always strip to bare metal for a resto. Sounds like Eric is repainting a previous job that he did.

Correct.

I think CitriStrip should probably work fine. Rust-Oleum 2X is a single-component paint (not to be confused with 2K).

 

You probably know this already, but just to clarify for anyone new to paint: A 2K two-component paint is one that uses a separate catalyst/hardener that is mixed with the paint to speed curing and promote molecular cross-linking that results in a hard, high-durability finish.

 

Most spray can paints are single-component paints, although if you don't mind spending some extra bucks, you can get 2K spray cans that have a built-in inner compartment containing a hardener/catalyst, which is typically activated by pushing a separate button or pin on the bottom of the can to open up the catalyst container inside the spray can. Once activated, there is typically a limited time window in which the paint must be used. 2K spray cans might be a good choice for a small job that only requires one or two spray cans, but for larger spray jobs, it is usually more economical to buy larger quantities of 2K paint and use a spray gun.

I’m currently working on refinishing a few parts on my ‘89 520H. This is what I’m using, it works pretty good.

I tried using the CitriStrip and found it not working as well and taking longer.

CitriStrip can be quite slow, but works well for a lot of paints if you're not in a hurry. I usually cover the object being stripped and let it work overnight (or longer). In most cases the paint literally falls off.

 

I've used a LOT of different paint strippers over the last 50 years or so...some of them VERY nasty to use. Different stripping chemicals work better with some paints than others.

How about setting the pieces in big 40 gallon trash bags?

I've done that. Works.
