Anyone used any of the aerosol gasket removal sprays
Do they work?
Any recommendations?
Better than paint stripper?
Cheers

Yes, it works.
About the same as paint stripper.
Still, you'll need a razor blade & some patience, but it does loosen the hardened on bits of gasket.

In the future, save yourself the hassle.
For the last 15 years, using Loctite 518 as a gasket dressing, my gaskets peel off like a sticky-note.

I gleaned it from a Rotax shop manual for my 800HO two stroke.

The best stuff ever.

It's for my latest acquisition BSA r3
Everything is glued down with god knows what
I had a job getting the sump plates off of the crankcase and the frame
I had real trouble getting the exhaust tappet inspection cap off
Personally if it has a gasket I always use grease
But I'm up against 52 years of previous owners and red hermatite !!

This is some nasty stuff. Did the job back before modern high-performance sealants.

I use wd40 and brake cleaner. Spray wd on and leave for a while

I use whatever I find to work, starting with mineral spirits, moving on to lacquer thinner, to acetone, to MEK. Use protective gloves when handling these solvents.

Never seen that before
I'm guessing it goes off solid?
Red hermatite used to be the go to here with a gasket cut from a cornflakes packet

Dries like brown (Portland) cement... very difficult to get off.

Was used on water pumps & thermostat housing to seal cheap paper gaskets.

CT1 multisolve is an aerosol that is vg for silicone mastic dissolving, so worth a try for remains of layers of whatever. From Toolstation etc. ( CT1 mastic is a remarkable product too)
Also, I have a small Sandvik hand scraper with small triangular removable head ( carbide) which is useful for careful scraping of surfaces.

Now there is a name I'd not heard in quite a while.
In 1994 I travelled to London, a 150lb. crankshaft crated & stowed below in the 747's hold.
Went on to Poole Dorset to repair failed machinery.
Had a great stay here: https://www.fjbhotels.co.uk/sandbanks-hotel/

This company was doing subcon work for Weetabix.

Bit late to the party as usual but I recently bought a can of Loctite 7200 gasket remover.
Used it on gray high torque (or whatever the flackery line is) Permatex. You spray it on and
let it work and sometimes two coats. It does seem to work but you still need a scraper, piece
of sharpened plastic is useful and safe. No idea how it does on Ye Olde Stuff.

A good sharp chisel and a steady hand works great for me, get it under the old gasket and it will remove the old stuck on gasket easy.

Yep I use that method amongst others
But god knows what the previous owner used on this bike for gluing the gaskets on
Especially on the sump plate of the frame and crankcase
