Eastwood Engine Paint Universal Aluminum

VHT high temp paints have ceramic in them..which when baked sets up like diamonds, well pretty dang hard anyway!! Point being its extremely durable, chemical and salt resistant, and the ceramic helps to effect heat dissipation from the metals as well. Ive been very well pleased with it.
 
Just painted a chunk of aluminum with VHT Engine Enamel. Two coats. Will let it air dry and then bake it.

Any suggestions for the test protocol? Keep wet with gas and see how long it lasts before any blistering?
 
I threw a carb top I painted and baked with high gloss black into a dish of gas overnight and nothing happened. Fully covered.
 
Lacquer thinner and brake fluid. See how long before it softens.

Well Dale, not sure lacquer thinner is a real world test. Maybe on the brake fluid. Gasoline is a definite.

How about if I dunk one end in gasoline like chuck did, then move to something more harsh?

BTW, test sample is in the oven right now...
 
08rangerdan, 20 minutes at 200? F according to the label.

Curing Engine Enamel
VHT Engine Enamel only attains its unique properties after correct curing.
Bake at 200?F (93?C) for 20 minutes.
The inherent heat of engine operation will also accomplish curing.

Ed, lacquer thinner may not be a real real world test but it will give you some sort of idea how chemical resistant it really is. Urethane holds up well to it so I would hope the VHT would offer some resistance to it as well. I would also like to know how well it does after about two weeks post cure. Other then that, maybe some harsh car wash detergent or laundry soap and a spot or two of brake fluid to see how it holds up to those.
 
My can of VHT says 1 hour at 200F. Did that and now it's back in at 250F for some additional time. Want to make sure this stuff is as hard as possible.

I'll do a cross hatch adhesion test first then dunk one end in gas. Tomorrow I'll dunk the other end in lacquer thinner. Good fun.
 
Quite impossible for me to do the test when it's hovering around 10? outside. Glad that you are doing it. :)

My current can says 2 hour..? Maybe the engine paint times are different then the other products
 
The metal sample was abraded using a sanding sponge followed by degreasing. Paint cured for 1 hour at 200, then 250 for 1 hour (next day). Paint was smelly while curing so something was going on there.

Test #1) Crosshatch test. The paint cracked and chunks fell off before even applying the tape. This paint is very brittle and doesn't adhere well to raw metal. Maybe a primer should have been used?

Test #2) Gasoline soak. Results TBD.








 
What is that paint supposed to be for Ed?? Is it engine paint? Am a bit confused as you said something about engine paint maybe being different.
 
It's VHT engine paint chuck.

Just checked the gasoline soaking test and the paint has already failed. It's soft and starting to lift on the edges after 1.5 hours. I'm sure it will survive some incidental fuel spillage, but you definitely don't want gas dwelling on this stuff though.
 
Wow..ive not had so much as one biitch about the engines ive painted with their stuff. The directions on the label that i took opics of and sent to Dale said something about using an adhesion agent. Dont quote me on the exact wording though.
 
Just looked at the can and it does say to use primer for best adhesion.

The gas soak test shows the paint is softened some, and peeling on the edges, but decently solid in the center. Will post photos in a couple more hours.
 
Lifting around the edges is what I would have expected it to do.

Hi Dale,

We have a silver/aluminum hi temp exhaust paint but I don't think it will stand up well to fuel spills and leaks.
We also a silver moisture cured urethane that will stand up to anything, except paint remover and high temp. as it was actually designed to be a paint over rust paint. There is one more that might work and that is our aluminum engine enamel, which is a high temp paint and pretty much resistant to fuel spills.

It didn't answer my initial question about colour match but at least they responded. I can't say that about Eastwood. :(
