Use almost whatever you like, as long as you don't scratch either of the mating surfaces. You can buy various products that aid removal of gaskets and sealants, then you could use a plastic or wooden scraper to be safe. However you can see in the kit below that a steel scraper is used which is fine as long as it is kept flat to the surface.

Frosts Gasket removal kit.

Which gaskets are you talking about in particular?

Those cheap plastic paint scrapers work brilliant!

I generally use a decent chisel! Keep it flat to the surface though. I also use brake cleaner to remove any residue. When reassembling use a GOOD quality gasket sealer along the lines of Hermatite.

Gasket sealant should definitely not be used on Every gasket though - and if the surface prep is good + gaskets aren't the cheapest set you could find, then there shouldn't be a need anyway.

In anycase - We need to know which gasket you're replacing really. Is it the rocker cover gasket (looking at your previous thread)

I remove any gasket with a stanley blade then get some wet and dry to remove the stubbon parts, leaves me with a nice flat, clean surface for the new gasket.

Worst part of engine building this is .

I like them scrapers though, been after one of them for quite a while.

i usualy use a stanly blade and paraffin or petrol to remove gaskets if the whole thing is in pieces, then seal the new one on with gasket sealant, if it is any of the ones around the gearbox dont use sealant as they are made to be a certain thickness,
