SPI epoxy as a top coat & how to fix a small area?

Hello,

I sprayed my sandblasted engine compartment with SPI epoxy last year and I was very pleased with the results. I'm using spi epoxy as a finish coat. Recently, I brush touched up a few spots with the SPI epoxy that I missed when I sprayed. All of the areas I brush touched up came out fine and unnoticeable with the exception of one (2" x 1") area, where I brushed on too much primer. My question is, can I wet sand this area to blend it and will it be unnoticeable? Also, what grit sand paper should I use?

thank you in advance for any help

I have heard people will take 2000 with soap and water lightly hit it and it will blend in but remember usually it takes 30 or so days for epoxy to lose some sheen.
 
thanks Barry, I'll give that a try.

Two days ago I sprayed a well sandblasted rear end with SPI epoxy. It's been drying for the past 54 hours at 70-75 degrees in a heated insulated garage. Can I turn off the heat at this point. I'm in upstate NY, temperatures have been in the mid 60s during the day and drop to the low to mid 40s in the early morning hours. Temperatures are increasing and are forecasted to be in the high 60s to low 70s during the day and 50s during the early mornings for the next week or so. The insulated garage on average stays 10-15 degrees warmer than the outside temperatures.

Regards

Ross

Yes you can turn off the heat.:) The first 24 hours is the critical time that you need to keep temps 65 (min) - 70 (recommended min) degrees. Keep in mind too that if you can get the part outside after you shoot it, the sun is one of the best ways to help speed the cure. 6-8 hours in full sunlight is roughly equivalent to 24 hours indoors.
