Thread: Tranny and engine paint

Tweet

Hi Room - Question re: Tranny and engine Block paint and painting.I want to paint my 700R4 Tranny and am getting a new 350 Performance Parts SB - want to paint them a matching color to some of the suspension components I've already painted (House Of Color Tangelo) how should I prepare the tranny and block, spray it, and will I be able to find Heat resistant paint to match their color? Should I Media blast the Tranny case before? And the block for a smoother finish? Many Thanks - CharlyG

I'v seen many high end custom cars have exzact matching paint as other non heated parts on the car, there might be an additive for the ceremic that makes engine paint take the heat, get with House of Kolor and see what they can do, there is a solution for your perdicament, I'v seen peralized golds go on engines and other radical colors just like your looking for so there is somthing out there.

Charlyg is right. You need to go to House of Kolor and ask their advice. Your chances of matching that color with some other brand is, as they say, slim to none . . . and slim just left town. One thing you have in your favor is that engines and transmissions don't actually get all that hot (relatively.) Most places, they're around 180 degrees or so. I painted the 454 in my A-bone with Sherwin Williams Sunfire, the same paint I used on the frame. It never discolored. Of course, Sunfire is virtually bulletproof (like Imron).

Media blasting won't smooth much of anything. It will take off rust and paint . . . and get grit into a hundred places you don't want it if you're not careful. If you want to smooth the block and transmission, you need the right kind of grinders and sanders and a lot of patience. It's mucho work. I did it once. Never again.

I've heard of people using high temp primers underneath of base/clear but have never really seen the long term effects of it . And as far as smoothing out the cast iron block. My friend , there are certain details that seperate the pack. Never be afraid to go the extra step when , most wont. Within the year my cutlass conv. with be HOK tangelo pearl , along with the smoothed out 455 and turbo 400 to match. Quality is in the build, not just how fast you can make your hot rod go....

I don't now if you are familiar with this company but they have a great supply for restoration and customizing.

Check it out they even have House of Kolor products.

Spray just enuff to cover the block and tranny and no primer is recommended on these items.Primer and additional coats of paint or clear act as a thermal insulator just like a blanket.These engines are not reffered to as air cooled but the air helps cool along with the liquid.

I have built 4 or 5 engines, where I matched the paint on the body. I used acrylique enamel paint directly over the block and tranny without any kind of primer. and never had a problem with it burning off anywhere.

this is the same color acrylique enamel that i painted the car with and ran it for 2 years without any problem. that blower gets really hot

I have painted several engines with either lacquer or urethane over the years and never had a problem. The only place I ever had any discoloration due to heat was around the center exhaust ports on a small block Chevy. Preparation is the most important step. I use Gunk very liberally twice with a parts cleaning brush to remove any stubborn crud. I follow the gunk with very hot soapy water and a scrub brush. Next I blow the water away with compressed air and then spray the engine with wax & grease remover, wiping it away with a clean rag before it has a chance to evaporate. Then apply the paint with no primer. I use just enough color to cover everything good and, if it needs a clearcoat I try to use just enough to get the desired effect / gloss without laying it on too heavily.

Have you considered polishing the trans. case? Looks good & it's not as much work as you might think if you have the right sanders.
