Hi team,

Ok, you could ignore them.
Only you see them.

Don't use acetone.
Stay light and friendly.
Meths is a start,
Liquid lightweight tools that deal with rubber are your best friend.
Going stronger, cut, I mean a paint cutting paste for paint, requires elbow grease or machine.
It's all an easy solve.
Leave it until you sell it.
It's a,working tool the boat. Unless it's more an item to be shown rather than used.

I'm just trying to get your expectations to be balanced.
Your problem is an easy solve. If you want work there are safe methods to deal with it.
Stay away from those who suggest acetone or similar, there not in your corner.

Cheers for the feedback guys - happy to report meths and some elbow grease did the trick 

Pic, forgot to reply,
Steps probably highlighted it.
Acetones are like many chemicals suitable for certain jobs.
It is further up the aggressive scale.
Unless you have the right knowledge base, start light and work your way up.
Or seek advice.

Pjc,
I understand
When I was younger we were and I'm not exaggerating. We're manipulated or directed to do things with products we should not of.

It's life,
I handled asbestos and chemicals to scary to describe.
What I learnt was not too believe all my elders.

Some of me elders realy new stuff and helped me learn to understand problems and risks.
Took a while but still on board on planet earth.

Self preservation is a real absolute goal.
