'87 Jaguar has cracks in paint

The hood on my Pontiac is developing the same thing. Menzerna FTG followed by Blue Natty's helped a bit, but it still doesnt look great. A full sand n repaint is the only true option, sadly.

I forget when Jag switched paint types....The #7 won't really make it look much better but it will be good for the paint if it's the old-school stuff. Watch what LSP you use as you don't want it to dry white in the cracks and you don't want to have to really *scrub* to get it out of them either. Again, other than the cosmetic issues, it's only as big a deal as the owner thinks it is. The checked paint will usually still adhere/etc. just like "good" paint at least as long as you're somewhat gentle with it, but keeping it well protected will help make sure it doesn't start really messing up.



Papi_Jay- Yeah, that does seem like the likely explanation, *if* it's a repaint (like on Bill D's car). Funny how some panels on older Jags just *do* this, even though the whole car was painted with the same paint/reducer-thinner mix and all the other panels are fine :nixweiss I recently saw an old 420 with a *really* checked trunk (uhm, "boot" ;) ) lid- all original paint and that was the only panel that cracked. Been like that for over 30 years...

Older '70s and early '80s car used laquer based paints that often exhibit cracking, but the cracking that I see on your pic is that of a repainted panel, normally a badly prepped surface in which the old paint is lifted when the fresh paint is applied.
