Curing fiberglass body

Hi all, i just ordered my first fiberglass body. A 1923 C Cab. I keep reading that the fiberglass bodies will have to be cured, and to let sit out in the sun for 2 weeks. My question is i live in NY by the time the body gets here it will be here at the beginning of November should i just leave in garage till warmer weather? Is there a way to cure it in my garage? What temp needed to cure?

Thanks

That cover will block the UV.. some dust or dirt won't hurt the body..Just make sure the body s setting on a flat surface is all.

Since this is your first fiberglass body I'll offer another piece of advice.

Before you do any sanding on the fiberglass, be sure to wash the body thoroughly. There can be mold release agent left on the gel coat and it will cause fish eyes in the paint. If you sand it without cleaning, the release agent can be forced into the gel coat.

I learned this the hard way on my T-bucket.

OK so here is what i got so far. Please correct me if i am wrong.

1. Wash body with mild soap and water.
2. Let body sit in sun for a few weeks to cure.
3. Wipe body down with a WATER based wax and grease remover.
4. scuff with 180-220 do not cut through gel coat.
5. fix pinholes with glazing putty.
6. Fix larger imperfections with body filler like rage.
7 prep for primer.
8 coat with epoxy primer, sand with 400
9. coat with primer surfacer/sealer block sand with 600.
10 ready for base coat.

Is this correct?
Thanks.

I would not use any glazing putty as your rage will fix any pinholes. A good primer surfacer will also work on minor imperfections..
