how do i remove asphalt/tar that has hardened already? i tried kerosene to no avail . . . but my procedure must have been wrong kaya di natanggal. kaya ba ito ng tar remover? thanks.
Tar doesn't really harden, it may thicked due to quantity, but di sya titigas...
The key is to scrape away the tar little by little from the top. Meaning, ang objective mo is not to scrape the thick tar off the paint, but to thin the tar to a level na matatanggal na sya sa paint ng kusa...
Visualize mo isang mountain, you scrape the tip of the mountain konti konti (using tar remover or kerosene and cloth) then keep scraping the TOP off until the mountain is level to the ground... At this point, just soak the tar and it should wipe right off...
How about on overspray of rusproofing paint on a 2 month old repainted surface? Will the bug & tar remover or WD40 be safe to use to remove those overspray?
