HOLLEY EFI DOMINATOR ECU
Dominator® EFI Vehicle Management Systems are intended for all engine applications, from street to unlimited high-end racing applications. In addition to the transmission control, drive by wire, and dual wideband oxygen sensor options, Dominator® systems have nearly unlimited capabilities to control any power adder, input, or output you can throw at them. Need to run a turbocharged, nitrous injected 8 cylinder running water-methanol injection? No problem with Dominator® EFI. How about control a 4L60E transmission as well as the fuel and spark on your street rod? No problem. There are also enough inputs and outputs to allow the Dominator® VMSs to serve as their own data acquisition and control module.

Wow this stuff works!!
Wow. What an amazing product.
I own a 1976 Bertram 42 aft cabin motor yacht. The previous owner had not waxed it in a good long time. I spent a weekend with four friends sweating and laboring using the traditional wet sanding, buffing, and waxing it's heavily oxidized finish. One of the friends helping was a former professional boat detailer. The results were ok. The wax job lasted about six months before it looked like crap.
There's a lot of controversy over Poli Glow. A number of the old fellows who sit around drinking coffee in the marina clubhouse swear that nothing should go on a boat except the most expensive and laborious traditional wax, preferably applied by a crew of of professionals. They universally ranted about the failings of Poli Glow despite having no practical experience. They also talk more than they actually boat, so I didn't listen to them.
I was cautious, and started with my heavily oxidized flybridge. I wanted to work my way top to bottom and I figured if I hated the look, I could stop and it wouldn't really noticeable.
It was easy to use. I bought the complete kit. Mixed the prep. Sprayed and scrubbed. Wow that stuff gets things clean and even.
I wiped the Poli Glow on with the provided mitt. Tip: really, you needs to let each coat dry before applying the next.
It was noticeable alright. From the dock you can now see an actual reflection of my antennae in the now shiny Fiberglas.
It's amazing. I did find that the more oxidized portions were thirsty as heck and took a lot of coats. The results are worth it. Application is way less laborious than buffing and waxing.
If you can wipe clean a countertop in your kitchen or galley you can Poli Glow like a pro. It's that stupidly easy.
Where the gel coat was reasonably smooth the product built a mirror finish. I didn't even put her on the hard. I applied it while it was docked. I couldn't have five that with a buffer.
My pro detailer friend was totally surprised at the result.
Bottom line: if you have an older sad looking boat this stuff can make it shiny and happy with minimal labor. Good stuff well worth the price.

Overall great product, especially on solid colours.
I bought a 33 year old boat that is mostly white gelcoat. Some of the white had yellowed in areas and there were bright spots where I removed stickers and hull numbers. The boat also has red and blue metal flake that was quite faded and gritty. The flake is large particles of metal or paint or whatever, not fine little glitter bits like they do now. I called Poli Glow Canada and the guy told me to use 600 grit wet sandpaper to smooth out the metal flake and then wash with the Poli Prep. The white came up pretty clean, but I had to use the sandpaper on some areas to take off the yellow. The Poli Glow went on really easily and quickly. When you are doing it, keep an eye on the the edges of the applicator. If the liquid starts to harden, wash the edges in warm water to get them soft again. I didn't do this and have some small bumps kind of like fuzz off a paint roller, which I guess is bits of dried liquid that came off the applicator. You will also get streaks if the edges are dry, but the next coat fixes that right away. Check after each coat to ensure it is smooth. I'm pretty sure a quick pass with the sandpaper would have removed the bumps, but by the time I was finished, I didn't want to mess with it. In the end, the white turned out looking great. The flake is definitely better than when I bought it, but it only shines at about 50% of original (compared to the flake on the transom which was in really good condition) and I was expecting better based on the before and after shots on their site. There are also some streaks in the flake from certain angles where I guess my sanding pressure wasn't consistent.

I am hard to please...especially expensive products...
K...So I have this 26 ft. sailboat. I have all the professional equipment you can use to restore fiberglass shine. However, a 15 year old sailboat's topside will usually have pitting that you COULD sand down and shine.. but this is a risky step as you think the gelcoat and if you go through, now you have an eyesore of an entirely different nature... My only problem with trying this was the idea that it would fade out shortly and possibly yellow. However, a bigger concern is continued breakdown of the glass surface. An over-riding concern. Wax on a surface that is pitted is usually short lasting and does shine well..good for 3 months, maybe. I bit the bullet and bought this after looking at it's competitors. BUY THE KIT, NOT JUST THE POLIGLOW. The cleaner worked better than any other I have bought. I don't know why. It just did. The scrubbing sponge is perfect for the job. I used a smaller dishwashing scrubber in tight spaces..it seriously was inadequate. This kit was made right, I'm thinking. Following the directions to apply per the bottle. I was skeptical about using a damp mit. I have done the entire cockpit area of the boat at this point with 6 coats and used maybe a half an inch of the product. And the boat looks absolutely AMAZING. Will this yellow? Will it last a year? IDK, but other reviews suggest positive experiences on both counts. Best of all, this will HALT the ongoing beating the topsides takes. (On another note, don't use this on nonskid. It's slick..just my opinion, maybe no more slick than new nonskid. But there is a really great product if you search "nonskid fiberglass surface restorer." Expensive but works.) Best description I can give you on how this will turn out is .. you know how good a surface that is aged looks when you wet it? That..but it stays. Yes, you will need 4-6 coats. But it dries very quickly and still doesn't use much product. At this performance level, the price was worth it. And I am frugal beyond belief. I would recommend that you do professionally buff any fiberglass surface with a good medium one step cutting compound and a professional buffer before you apply this to get best results. DO NOT USE THIS ON SURFACES THAT ALREADY ARE SHINY. It says so right on the kit. I also agree your smoothest outcome will come at room temp vs applying int the sun or significant heat. It dries quickly and doesn't even out as well before drying. Still, it will look great.

YOU WILL LOVE IT!!!
This is the best product I’ve ever used on our boat! We have a 26-year-old Tige wakeboard boat that had heavy oxidation and water spots. In addition to a heavily faded gel coat. I spent a few hours working on it and it completely restored our boat! I got the recommendation from my father in law after he used it on his RV. The results speak for themselves. I highly recommend this product!
