Looking for some advice as to the suitability of using Minwax spray laquer or a nitrocellulose laquer as an isolation coat between two old masters oil stains. I am using an Old Masters gel and wiping stain to create a faux burl finish and will then use another Old Masters wiping stain as a toning stain. Plan to finish coat it with more Minwax spray laquer and then rub out to a desired finish. Ideally I would use shellac, but just can't get any where I am at present.

We use a NC sealer cutted 200% with lacquer thinner (wash coat)
Just one pass , between oil stain or wipping stains, to avoid the second color removes the firs one
Others coats must be NC sealer/top coat to avoid cracking

Thanks for the input Mauricio. How much drying time do you give the first coat before applying the wash coat? And can you build up the NC finish coat the same way as any other laquer to rub out?

Simon, we wait 2 - 4 hs using a hot air fan, the first stain coat is more difficult to dry, depends how much stain you had applied.
The following coats dry really fast.
If you use a clean spray booth and drying room, there is no need to rub out.
Just some wool wax, if necesary

Oh no Simon, you will have to apply several coats to reach the desired gloss.
Maybe you will have to spent some time doing samples untill you find out a good finishing schedule.

Thanks for the clarification. That makes sense. I was planning on applying between 5 and 10 coats of the minwax laquer.

I'll post some photos from the finished project. It's only an old cutlery canteen but it was the first thing my grandfather bought when he was demobbed after the war. They had handed in all their good cutlery and anything metal they could spare to make planes, so it I want it to look good so I can hand on to my kids.

amazion more shellac than you could ever use

They won't ship it to Mexico John sadly.
