Corvette with SMC

[Mission]

Edit: Also you can see the spots where the SMC ends and paint starts, where it's feathered.

Why did you not strip? This could be a problem down the road on a vette, it not like doing a metal body, just saying.

That's not good and thanks for the reply. I do not want any problems down the road. I should sand ALL the old paint off where there are multiple layers? The bottom half and the bumpers still have good OE paint.

Edit: I have sanded down to the OE base coat or further where there are multiple layers.

We sell many vette shops, and not one has ever admitted to me that they don't strip the outside; it would be suicide for them not to.
The gm memo goes back to the 60s. Shine may know the date or Dub if he sees this.
Factory paint and one paint then must be stripped.

I understand now what you said earlier. I didn't know I had to go to the bone. I found this out only using 1 quart of epoxy. Thank you.

Okay. I have my hood sanded to the bone. I washed it with Dawn twice, rinsed and blew the water off. I can let it sit for 24 hours and apply epoxy. Is this correct? Thanks

Edit: It's in the mid to upper 80's here.

This is a tough one as I have no experience hearing someone doing your process on SMC????
Fiberglass it is done a lot, and you would be perfect.

Maybe someone here has used that system on SMC.
If you gave hood to me, I set in the sun for at least a day to hedge my chances.

There should be answers from others who know if you're okay.

Edit,
Just a note for answers full SMC started on the C4 vetts in 1984.

man thats asking alot from my old brain . it was early 60's i think. factory paint did not like solvents over vetts . it would ghost something terrible.

The main reason besides wrinkling was the expansion and contraction of the glass, and with three layers of paint jobs, it would bubble in the first three months to 6 months on the flat surface. (Unless stayed inside)
Remember, each paint job is also expanding at a different rate than the other.
The painter would get blamed, and he would spot fix say, the hood, now it goes to 3 hours to 8 hours of sunlight and blows up again.
