Engine Block painting
What is the best way to prep and then paint a Chevy engine block? Looking for info on primers, types of paint, correct colors, etc.

It's a real pain to work with, but I love the POR products.

Re: Engine Block painting
If it's a fresh rebuild, the prep is mostly done when its tanked to clean metal. Otherwise, its tedious work to prep an engine. A lot of cleaning and scuffing in all the nooks/crannies.
We paint engines with pretty much the same process you would use for the outside of the car, and with the same products. Epoxy/etch, sealer/primer, BC/CC (sometimes single stage) with SW product. Dont know the exact terminology or product #s, I dont do the paint/body stuff.

Re: Engine Block painting
IF you are over restoring a car then by all means go with the primer ... epoxy combo... however if you are looking for an authentic restoration then a light covering of an original type product from a spray gun is how they were done at Flint and Tonowonda. If you look at orignal unrestored cars they have minimal paint on the engines.
Here is a link to pics of a very low mileage LT1... http://www.chevynova.org/1970LT1_Engine.html

Re: Engine Block painting
I understand the lighter the coat of paint, the longer it will last because it allows the heat to evaporate. If you load it up with primers, base & clear, it will peel off quicker. Any truth to that?

Re: Engine Block painting
No primer was used...
Just get a can of hi temp engine paint, and go for it. Make sure the surface is clean. No fancy paint or anything - later on, it makes it easy to touch up too.

Re: Engine Block painting
All good info. I was either going to simply spray a hi-temp paint or go the primer, base coat etc route. I will probably just use a can of hi-temp paint.

Re: Engine Block painting
I use plasti-kote engine enamel and gray engine primer. just a light coat of primer and you wont get the cast bleeding back through the paint.
ENGINE ENAMEL and Primer Resists Temperatures up to 500°F (260°C). Race Tested. Will not Burn Off, Chip or Peel. Oil Resistant. Color Choices are Exact Matches to Original Engine Manufacturers Standards.

Re: Engine Block painting
How does powder coating look? A local shop will do engine blocks, heads, etc. It should be fairly durable.
