Getting ready to install the 289 in my 65 have been re detailing. 13,000 miles sure took a toll. Couldn't find a suitable LH stock manifol so got a deal on a set of new. They had a waxy substance on them A. washed them with hot water B. Wiped them with L thinner and did same with those doofy 65 manifold locks. In the oven cooking at 500 for an hour. So far, no bad smell. Using a product called castblast spray for manifolds.

I often read here about people applying lacquer thinner before paint. What's the purpose? After washing in water, I always splash on alcohol (usually 70%) since I believe it draws off any remaining water and evaporates it away. But that's just my theory. I'm not sure it works.

Alcohol works good. I washed them with hot water and kitchen detergent. They were dry in the sun but I wiped them with thinner for a final cleanup. By the way, they came out good. And after an hour in the oven, the house DID stink! All window down and AC off.
Painting interior panels, wash them with soap and water but use alcohol also. Not to pick up moisture, but to get any final cigarette film and oil from hands, etc. Doing this pretty much eliminates getting fisheyes in the new paint.

Is that a 'clear'? I haven't yet seen a coating short of ceramics that last a reasonable amount of time. Your stuff sounds well prepped, I'm most interested in the results

Oh, LOL on the 'doofy' manifold locks

mellowyellow - Here's a suggestion, check out either of the following sites:

http://www.por15.com
or
http://www.eastwoodco.com

Both companies make coatings for high temp
areas, ie. exhaust manifolds, headers, exhaust pipes, etc.

Eastwood, in my opinion makes the better of the two, but I've not used POR-15 on manifolds. Basically, you just paint it on and then run the engine.. It'll stink for a little bit while it cooks on, but after that you have a solid coating. I wouldnt do it in an oven though... the motor will put out much more heat than your home oven ever will.

Been using Cast Blast for several years. It is gray-same color as the cast finish spray paint for castings, hood hinges, etc. The High temp blast is 1200 degree tested. It's lasted 3 yrs of regular use on a pair of hi po manifolds, is cheap, looks accurate and is durable. Wouldn't change for any other brand. Stuff is marketed under different names-made by Seymour Paint Co., Sycamore, Ill. Pric about 6.50 per can. (Oh my God!) forgot! Had a HOT grrrl friend from there!! LOL!!

Like anything else, the surface needs to be prepped for good use. Nasty exhaust manifolds should be bead blasted for BEST results. These manifolds were brand new, just required cleaning.

Directions on can say to heat to 400 for a cure to make it surface durable. I did 500 for an hour. Engine can do the rest.
