Repainting Cast Iron Trivets

I had been wanting to play with Rustoleum’s High Heat Grill paint for a while now.  I had to wait until I had something to paint and the weather to break. 

This antique sad iron trivet has been swimming in the molasses and water rust bucket for a while, and I picked and had a skim coat of rust to scrape off.  After fishing it out of the bucket, I gave it a good scrub with steel wool and a wire brush. No matter how quickly I dried it on the stove, it immediately got a powder coat of flash rust, so I applied a light rub with a rag soaked in mineral oil.   If this item would never be exposed to food, soap and water again, it could live with just a coat of mineral oil from time to time, but I want to use it for hot pots and pans. it needs a very light seal coat of high heat paint will keep it free from moisture.  Most of the mineral oil had been absorbed already, but I gave it a good scrub with a dry brush and rag to make sure the surface was good and dry for painting.  

The filigree trivet is just a cheap thing, but I thought it was pretty.  All those pretty nooks and crannies are a challenge to keep rust free.  I used a skinny wire bottle brush to get into all the corners before painting. 

I was pretty astounded at how quickly the High Heat paint dried.  Unlike other opaque enamel paints, it only took a couple of passes to completely cover the surface of each trivet.  I do expect the surfaces touching the bottom of the pots to wear off a bit and need another coat down the road.  The antique trivet looked great in flat black, however I keep thinking the decorative trivet should have been done in gloss coat.  Rustoleum makes a High Heat Gloss Black for 500 and 1200 degrees but I have to order them special from Amazon.  I also want to order their High Heat Clear Coat which may actually work better.  If I get a tole painted trivet, I think the clear coat would be best to preserve the paint colors.
