![]() Some tips for you all, so that you don't have as many problems as I did if you order:ġ.) If painting aluminum, do not use the VHT engine primer. Since I have so much time and money invested in this first paint job, I will simply be forced to try and patch the imperfections (which is the ONLY reason I keep buying this stuff). ![]() My problem is that the engine is mostly covered with this stuff and so I am either forced to redo the entire thing, or try to make what I have on there work. I was quite surprised, because most of the other areas did not get durable like this. For instance I accidentally dropped a flat head screw driver on my valve head cover and it did not chip from the impact. There are some areas that seem to have cured to my expectation. I am not exaggerating when I say that I was surgically clean with this whole endeavor. I even hung up plastic sheets and created a clean room while I did this. The bubbling would indicate impurities or oils under the surface, but I don't see how that is possible since I essentially did this all in a clean room, wore rubber gloves whenever I handled the pieces, blasted, and used aluminum specific engine prep liquid. In many areas I've still experienced chips (not even just on corners), easy scratches, and worse bubbling. Also, it should withstand scrapes from moderate pressure, say like a boot rubbing against it. Basically just trying to simulate the every-day bumps and bangs that the paint my see. My expectation is that it shouldn't chip off from something small dropping onto it such as a small M8 socket from reasonable height. It will, in some places, but only after a full cure with temps up past 300-400F (like when you run the engine). This stuff ought to be able to hold up against minor chips and scrapes. Going into this I knew it would't be a factory finish and there are some other durable routes out there, but I needed a variety of colors for my custom motorcycle rebuild. It sounds simple, but there are some huge issues with the performance of this stuff even after spending hundreds of dollars on prep, paint, and supplies. ![]() What really drives me nuts is that I reached out to VHT several times and either got no response, or got very poor support from a rude customer service rep. I probably put 5-9 total layers on my application.Ħ.) Bake in oven (tried 200F per VHT rep's instructions, but 350F worked much better) If additional coats were needed, I waited as per the instructions state, lightly sanded, and reapplied. Follow the instructions to a "T." Recoated within the time window as specified. Light coat, enough to cover, but not build up.Ĥ.) Painted. Here's what I did:Ģ.) Use surface prep liquid (oil removal)ģ.) Primed, several times (tried both VHT high temp and self-etching primer, per VHT rep's advice). I'll spare the details, but will clarify that I am using the method for painting specified by VHT and my local paint pros. I have had so many frustrations with it at this point, that I wish I didn't have to use it anymore and could go back in time. However, having now purchased roughly 2 dozen cans of this stuff for my motorcycle engine rebuild and two other small projects, I can easily stay I won't be using this stuff anymore. There is also some sort of value because if you want to refinish and engine there aren't really many options unless you can afford to take it into a shop and pay them $2000. On the one hand it is relatively easy and allows guys at home like me to redo projects with that professional look, even if we don't have the professional equipment. To achieve the ultimate in protection and quality, follow the VHT Engine Enamel Coating System which includes primer, paint and clear coat.I have a real love/hate relationship with this VHT paint. ![]() VHT Engine Enamel only attains its unique properties after correct preparation, application and curing (as per instructions on can).
