SPI Epoxy as Sealer - Barry K??

nova69 · #1 (**permalink**) 10-02-2006, 10:53 AM

I am going to seal the Nova with SPI Epoxy reduced 20%. Question is - how much time do I have before I MUST Base it? There might be issues of weather, temp, etc. to deal with after sealing. Thanks.

Seven days unsanded.

If it stays in the garage after 7 days you can use a gray scuff pad before base.
If car is outside or driven you must scuff and re coat with epoxy.

I'd suggest that if you have to leave it over an hour. You gently run over it with 1000 grit (with a little water)and knock off the lumps, trash, and texture. Then base it. Why not take advantage of a dry substrate when you can. Just an idea. The smoother the under-coat the smoother the top-coat.

There is no reason for him to touch it unless he has some trash he has to remove or If it were going to be a top end show car finish, then yes, I would say wet sand it with 600 the next day and base.. Is that the case here??

If eveything is right, the epoxy should spray and appear like a base coat. If that is the case, barring any imperfections, like trash, orange peel, or runs, like Bondoking said, there is no reason to sand it, unless you are over the 7 days.

How about how soon can you spray over it? I like the idea of epoxy as a sealer but sometimes the overnight wait can be a problem so how soon can it be safely top coated?

According to the Tech sheet,

Spraying:

Spray one wet coat for normal applications. For special projects such as restorations

Spray one coat and let it flash about 10 minutes at 70° degrees or higher. Then spray second coat for maximum corrosion protection. If one coat of epoxy is used wait 30 minutes before painting. With two coats of epoxy wait 60 minutes to paint.

Some where I got the idea that waiting overnight was required, wish I had of asked sooner, Thanks

Thanks to all. The weather turned to crap today, and I'm leaving town for a while (going to Ireland for ten days). So everything will have to wait until I get back. I just don't want to spray anything with cold, rain and high humidity out there to spoil it all.

You may have gotten that from "The Perfect Paintjob". In there, everything was to the extreme. I was doing that at first.

Most epoxies used as a sealer (additional reduction) will have recommendations of 30 minutes to four hours for applying base.
Of course overnight is always best and as pointed out overkill.
