That's what I used. I had to hand scrub the old paint off, I bought that car with already flaking paint. Cleaned it, scrubbed it, cleaned it etc over about 3 days, then painted it with 2 coats. Now it looks fantastic and have had no issues.

just take your time in prep, get yourself a few toothbrushes and wire brushes and start cleaning the heck out of it (scrub and clean it with Lacquer thinner)

feel free to go to my website and look under the shop cars tab and take a look at the blue car ..... I have pictures there of cleaning and painted LS1

Thanks guys for the info. One other question, did you primer first or go straight to paint?

Thanks again.

We use VHT eng paint with good results. I primer first

The process we use on all engine/trans/rearends, etc. Clean the crap out of it!!! Use degreaser or similar and get it clean. I usually have a piece of scotch brite and I get in all the little nooks and cracks! Then get some wax/grease remover and wipe her down, even a second time is recommended on used parts. On bare metal you NEED a good "etch" primer first, then you can follow with a sealer, then base/clear (or single stage).

All automotive paints/clear will take any heat a motor will create. As long as the "prep" is done correctly the finish will a long time.

I second that. Same process I use and never had any problems with using automotive basecoat clearcoat system. It is a must to use a good etching primer.

Guys here is pic of the heads getting smoothed. Do I need to make sure that any sand scratches are totally removed or will the primer fill them in?

I would media blast if all possible or get it hot tanked. I like using Sherwin Williams GBP 988 etching primer in aerosol before paint. And yes, automotive paint will hold up just fine on the block, can't say that for the heads.They will need high-temp paint.

Thanks for the input guys! Prior to using the etching primer, what grit would you recommend to used to go over the bare aluminum to create some bite?
