Vintage Baseplate Paint Restoring

[massmagic]

Hi to everyone!
I'm trying to restore a baseplate 32x32 that comes with set 6399 (Airport Shuttle).. BL part 309px2

While cleaning a red ink stain on the baseplate with isopropyl alcohol, I noticed that in a zone of the baseplate the white line of side road was almost removed by alcohol.. never happend with other baseplates.

Can someone suggest me with kind of white paint can i use for restore the part of paint that alchool has removed?
I can't find any infos about what kind of paint was used by lego for those vintage baseplates..

Thank you in advance and have a nice day.

I would use multiple thin coats of a white acrylic primer. I use Vallejo paints on most plastic models I paint (not just LEGO), but for this I would stick with just the primer. It gives a flat, fairly matt finish and is quite hard-wearing.

Hi MAB!

Thank for your answer, I will try a Vallejo white primer :)

Do you have some infos about which paint was using lego for baseplates in 80-90?

It's really strange that white line paint was removed by isopropyl alcohol ..

Probably just a standard matte acrylic paint. Printing with UV-curing paints wasn't really a thing in those days and enamels don't respond to isopropyl. Any modelling acrylic like the one @MAB suggested will do.
