Gentlemen and ladies, can I ask for your advice please?

The brand leading chemical paintstripper in either the yellow or water washable green containers, you know the ones I mean without identifying the make simply don't have the strength compared with, say, five years ago.

Can somebody recommend another make which is good at stripping car paint?
I could make up my own caustic soda mix but would prefer not to.

What do you all buy or use?

Thank you.

Do you know what the paint is? Caustic soda works well on oil based paints, hence its use in commercial house door stripping.....

I have two vehicles to remove the paint from.

The first is my Jaguar Mark 2 which was sprayed in the 1996 version of isocyanate and lacquer finish.

The second is my 1954 Land Rover in what looks like synthetic enamel over another coat or two of synthetic enamel and below those layers is the all but impossible to remove Land Rover etch primer with any chemical stripper.

Rust-Oleum Aircraft Remover works well.

I read good things about "Starchem" chemical paintstripper, as it somehow contains the stuff that was removed from the stripper to which you referred in the opening post. Alternatively I also read that you can add "dichloromethane*" to that non-functioning stripper to bring it back up to what it used to be before said chemical was removed.

( * do your own research as to the correct chemical name and amount to add, I will not be responsible for missing eyebrows or limbs)

Thank you for your answers gentlemen.

The Rustoleum Aircraft Stripper appears to be unobtainable at this time. Amazon has no stock and future supplies look uncertain.
If anybody has any ideas of where it can be bought in the UK then please let me know.

The Starchem product looks the most promising but I had a thought this afternoon. I'll try the local auto paint sellers and see what they have to offer.

I like Mike Edward's suggestion of adding dichloromethane to what used to be the brand leader. Apparently it was used as an anaesthetic in Victorian times.
Could be very useful!

I'm currently tidying up the Stag, it was painted in 2k, tried the new Nitromors , it did work but was slow and required multiple layers, I suspect the dichloromethane in the old stuff was a far more powerful solvent hence the old stuff would go deeper.

I ended up taking the boot and bonnet to SPL for stripping. For the wings I used a flap disk on an angle grinder, they are available in different grades, I also purchased a dust extractor that fits on to the angle grinder and connects to a vacuum, it was only about £15, not perfect but does minimise dust. I still needed paint stripper for places where the grinder wouldn't fit. It's actually quicker than chemical stripping.

I'd be interested to see if there is an effective chemical stripper for 2k either off the shelf or home brew!

You could type; 4.5" paint stripping discs into utube, watch the various videos then look on eBay or google.
They work fast and effectively.
I found that one disc would strip about one square metre down to bare metal without gouging, grinding or damaging it.
I can't imagine body shops messing about with chemical strippers these days when you can use these things.

I've used those discs that look like sponges, they're effective but there's a fair bit of mess as the bits of paint have to go somewhere.

I used these = https://www.youtube.com/watch?v=LZhFQub3KDQ

They come in different size,s .

I also used a electric heating gun, together with a sharp metal spatula.

Easy way to do it, and much better.

I've tried those discs but found them short lived and expensive. That was a few years ago now so I guess they could have improved, but I don't feel like taking a punt again tbh.

This is the one...just like the old stuff...maybe better in my experience,
certainly cheaper. Smile

So that's how they get around the reduction in the useful component: "This product is intended for sale to non-EU Export customers only "

That's one I hadn't heard of before. Thank you colwyn500.
I've bookmarked that for future reference.

On Sunday night I ordered 5 litres of the Starchem Synstryp and it arrived on Tuesday morning. For those of you who are considering buying it then shop around. I paid £26 but have seen it as high as £36, mine came from "a well known internet auction site".
Apparently if the intended use is for "professional operators" you can buy paint stripper with dichloromethane.

I have still to ask at auto paint suppliers and will report back as soon as I have some information for you.

For those who may be interested, I called in a local auto paint supplier this afternoon and asked what was available as a chemical paint stripper.

The supplier's owner shook his head and said there's no call for chemical strippers these days. The body shops he deals with all use stripping discs in varying grades of coarse to fine and in different sizes depending on the rotary or DA sander being used.

I Googled "Chemical Paint Strippers UK" earlier and there appears to several on offer.
