Scandanavian oil / marine varnish mix

Hi all,
I am new to oil finishes and have been using a mix of Scan oil , marine varnish and turps on a Marri table ( wipe on wipe off after 30 sec to 2 min or when starting. The mix brings out the natural look of the timber whilst giving a bit of a protective/reflective coat. I do at least 3 coats on the top up to 5 or 6 after sanding to 400.

This has generally worked well until recently.
I applied the 3rd coat and was foolish enough to then use the panel saw which promptly covered the top in fine sawdust which seemed to bond a bit to the top as it had not fully dried.(Oiled about 3 hours before)

Dilemma !

I decided to sand with 600( to try not to cut through previous layers) to try to remove the dust before applying another coat.
The paper clogged a bit and left little circular squiggles on the top, I changed paper and had a better result removing all the offending sawdust and squiggles.
I then applied another coat wipe on wipe off.
Upon drying there were raised ridges along the join lines where the boards had been glued together!
Is this because the oil mix cannot penetrate the glue and hence "sits" on top ?
Buggered if I know - it seems to be removeable with fingernail scrape but got me wondering about steel wool and it`s application.
The Question is (Apart from the Organoil Hard Burnishing oil and it`s application method and process) how do you achieve a uniform (when viewed on the right light reflective angle) finish on an oiled table using a mix that has about 10% marine varnish ?
Is 0000 steel wool the answer .
Or perhaps its in the applicator/ application method- I just use a clean cotton rag.
Any advice coming from experience would be appreciated
Cheers
