Ablative means that it will continually shed the outer most surface of the paint
, revealing fresh unexposed paint
to continue its job. Obviously, putting hard paint
over it, would be shed off as well.
compatibility is tricky. Not all hard can be painted over all hard, etc, etc. I take it that it was last painted by a prior owner. Any way to get in touch and ask? Paint manufacturers are pretty good at publishing what can be painted over what. It can be brand and formula specific, no totally safe rule of thumb.
If the current paint has worn down to where skips need touching up, you are probably in need of a full paint job, even if the rest looks intact. Consider stripping, so you know where you stand.
