2nd Build SHB-4

[McCreed]

The front is fine, even in the warm weather, it's the satin finish on the rear and sides that just doesn't want to play. I have another project waiting so when I get round to that one I'll be biting the bullet and making it all gloss. Probably go back to tru-oil as well.

If you want a satin finish, there's no reason you can't achieve it with an oil based satin poly. You will likely need to sand the back & sides down to bare timber again, as trying to apply over the existing tacky stuff is just asking for trouble IMO.

I would really encourage you try my 50/50 mix of satin poly and mineral turps (aka white spirit in your country) and wipe it on.
You can also go 60/40 poly/white spirit for the early coats to get a bit quicker build, then go 50/50 on the last few coats for a smoother more flowing consistency.

If you choose Tru Oil for reasons of familiarity and consistent results, you can de-gloss it with wet sanding to have a more satin-like appearance. However it will not give a true satin finish because real satin clear coats contain a small proportion of solids that diffuse light (minimise reflection).

Good to know, thank you. I'm leaning to the easy (for me) option with this now.
On the more positive side I like playing it and it's found its way onto several songs that will be on the new album later this year.
