It might be better next time to paint your vette with bed liner. It will make a better non-skid surface while using it as a ladder as well as take being scraped with a shovel better.

LOL shine ,Now how would you know that??? I've made a few batches of jelly myself...
I've also woke up in the middle of the night and thought I screwed some up and really didnt...(lost a whole nights sleep) this may be a case like that..but the worst is when it dosent dry and you wait a week praying to the paint gods for a miracle then have to get all that goo off...

no need to thank me for the help as myself has painted several thousand cars i have ran into problems myself. the longtivity of the clear will be shorted for sure but it will last for along while anyways. any one that knows anything about solvent borne paint would know everything becomes a soild and cannot be sanded off as coats. if this were a 50000 dollar show car i would tell you to strip the whole car and start over but you states it wasen't. i am a rep for dupont/spies hecker solvent and waterborne paints and have seen many things, this kind of stuff happens to alot of people that dosen't paint day to day.

I'm happy to be back, now that I don't take this stuff so seriously.

But it's still astonishing how much utter balderdash gets accepted as fact around here!

LMAO!

Who cares what other people think/say. When people dont hear the answers they want its only natural to insult others and whine about anything they can.

Back to the issue at hand. I have the entire car blocked out with 1500 grit and will block it with 2000grit before laying down my last layer of clear.

I will make sure I dont make the same mistake twice.

Thanks for all the help from everyone.

It does not matter. The OP is content with your advice, such as it is.

But those who are at all concerned with the durability of their finish would be well advised NOT to leave uncatalyzed clear as their topcoat. A situation like this might actually be less serious with a showcar that will have very limited exposure to the elements, but on a vehicle left outside, it will very likely prove to be a problem in very short order.

I will grant you, there will be some intermingling with the previous coat, but there is no way to prove that this is sufficient to initiate sufficient crosslinking of the last coat.

There would be NO WAY a vehicle with such a serious flaw would leave my shop, ever.

If there is any truth to this whole story and we are talking Urethanes as I don't know Nason number or care enough to look up., so could be enamel for all I know and then what was said could happen.

If urethane, cannot and I repeat cannot mix itself with an ISO that is mixed in a previous coat, unless they were puddled back to back and then would not mix but may harden to a degree but it would have to be a soup bowl action.

Some wax and grease removers will mix with clears, one containing LDS or 300 series types, as a matter of FACT some crap clears use them as cheap fillers as they are mild and do no good or harm but a cheap way to take up space. Ever used a cheap medium solids clear and next to a high solid high price clear, the cheap clear looks thicker? There you go, LDS will do that for you and you save about 50 cents a lb. A fake thickener, for lack of better words.

SOOOOOOOOOO, if this was a urethane, the only thing that could have happened is he did mix some activator with the clear and may of mixed some wax and grease remover with it, the wax and grease remover most likely had a higher then "urethane grade" moisture content and acted as an accelerator
and that is why the clear was so hard the next day to wet-sand.

My best guess as none of the story adds up.

The story is short and simple. Zero hardener, mixed clear with wax remover.
Already had 2 coats of clear on the car.

Still got hard. Simple as that, believe it or not. I am 100% sure I did not put any hardener in the clear.

I think god was looking down and said Damn! This poor guy just messed up royaly.... He needs my help.


I also checked the left over clear that I messed up. It has not jelled at all and is still in liquid form in the sealed container.

Hope it works out but remember an unactivated or under activated clear will dry inside to touch but when pulled in sun will turn soft and then dry again when you pull it inside and will never cure just dry and undry, for lack of better words.

haha That will be a horror story. Thanks for letting me know, I had no idea.

I sanded the sh** out of this car. I am hoping that I took off the entire last coat. I know that I messed up bad and all I can do know is see what happens and hope for the best.
