I tried garage floor paint from Screwfix, then 2 pack resin based paint and also tiles and the latter have worked best for me , they arent perfect as heavier cars can cause them to move about a bit and in hot sun they expand but i've fixed mine down in a few places with gripfill and they seem fine, they are nice to work on
They have been down more around 12 years off and on as I took them up for a bit due to them moving with the 370z but they still look pretty good
They are the same as Jez has at H-Dev and they are still alright there , i bought mine off him as he had spares left over.
