Allstar Performance ALL10680 Radiator Fin Comb Kit, Black

I wish I had been smart enough to take before/after photos to show you. I used this to straighten the fins on the AC unit on my camper. This unit did have fins with a zigzag pattern, and this tool worked just fine (others reported it not working). I spent maybe 90 minutes working on the unit, and it looks almost brand new. The fins weren't in terrible shape to begin with- maybe a 60/40 ration of good/smashed. However, after using this, I would now say it is more like 98/2. There were just a couple fins that were smashed enough that they basically tore and couldn't quite be straightened again. I just took my time and was meticulous and am super happy with the results.

I had an AC with some badly smashed fins on the A coil, and making passes with an old credit card , one fin at a time from the edge of the undamaged areas "into" the smashed area to straighten the badly crushed fins, and then using this radiator fin comb to "fine tune" the fins, is a slow-but-sure way to get the job done. I didn't have any problems with the fin comb teeth breaking off - if the fin is smashed so badly that the fin comb won't go through, use the old credit card or any other similar stiff, flat plastic (like a piece cut from a Tupperware container) to straighten the fins, one at a time from the undamaged edge, working towards the damaged area, and then follow-up with this fin comb. If the fin comb won't pass relatively easily from one direction, flip the comb over and pull it in the opposite direction.

Does it work? Yes. Is it easy or efficient, absolutely not! I race a dirt stock car, and the radiator takes a beating from flying dirt, rocks, etc. I figured I would try this to try to straighten out the fins in the off season. Trying to insert this comb into a full series of damaged fins is impossible. The gap between the little plastic teeth has nearly 0 clearance to the fins, so alignment must be perfect. If a bunch of fins are bent, it won't go in. The only way I found to make this work was to get the fins close, one by one, with a single point pick, and then walk this along one damaged fin at a time. Not at all efficient! If you have a small area of damage you are looking to correct, this might be fine. But forget about doing anything with more prolific damage!

The fins on my outside home AC unit were damaged in a hailstorm. While the AC works, the bent fins reduced the unit's efficiency, so I purchased the fin comb kit to straighten them. The product worked as advertised, but the job is much harder than shown on some Internet videos. Let me summarize my observations as follows: 1. This was the only product that I found that had a fine enough tooth spacing. Most only have combs that are as fine as 15 teeth per inch, whereas I found that I needed 20 teeth per inch for my unit. You will need to measure the fin spacing to make sure that the fin spacing is within the range of the combs that are provided in the kit. 2. Severe dings required that I first bend open the fins individually using the nail file tool on my miniature Swiss Army Knife. This was a very tedious, but a very necessary, process. 3. Starting the straightening correctly is very important. It is necessary to line up the tool carefully between the teeth, or it will actually bend over some fins, hence the need to pre-straighten the areas where the fins were severely dinged. However, even then I could not completely straighten some of the severely bent fins. Some were almost cold welded together. 4. The teeth on the tool are relatively wide, making it difficult to align them with the fins, especially because the fins were not straight to begin with. When you align them properly and use a straight motion it will straighten the fins as advertised. However, the protective metal grill means that only a few inches at a time can be straightened. You could remove the grill to speed this process up, but I was warned against doing this as it is not easy to do and to put back properly without damaging the AC unit. 5. I can now better appreciate the estimate of over $400 that the one repair company willing to make an estimate for this job wanted to charge for this. Because this was over three times the amount allowed by my insurance company I decided to strengthen the fins myself. 6. The teeth on the scraper are made of plastic (as is the handle), and it wears straightening sharp metal teeth. Thus, you should not expect to be able to use a comb more than once (twice if the damage is not too great) for a unit like mine. However, given the low price of the kit and the high price that I would have been charged to make the repair, this is not a serious deficiency. All in all this kit works, but the job is difficult and the kit will not last for very many repairs. I am still looking for a tool with narrower metal teeth, with 20 teeth per inch, but I have not yet found it. This is the best tool for this job that I have been able to find. Actually, metal teeth might not be the best choice, as I can imagine that the sound of them scraping on the metal fins might make the job extremely unpleasant without uncomfortable hearing protection.

We use this for our window air conditioners and works great!

I hate to leave negative reviews, but this is junk. In less than 5 minutes, we ruined 2 combs by simply combing out our ac fins. Spend a little more, and but a more sturdy comb. This is cheap plastic that can be bent with your fingers. :(

It works well and has many head attachments, but feels a little flimsy

This tool works great for straightening out the fins on a radiator. You almost need to have the plastic comb so it doesn't damage the fins. Comes woth multiple attachments for different fins per inch. Make sure when you use it that the comb teeth are each in their own slot or you will bend the fins. Take your time and work slowly. Dont force the tool if the fins arent moving. Simply use a little pick to get them up, then run the comb through them.

Worked great, the A/C on our horse trailer was in rough shape this little tool had the right size and powered thru some heavy damage and never broke a tooth. Handy little tool but lacks a case

فاشلة جداً بدال ماتصلح المسافات بين المبرد توسعة وتشققه استخدمت جميع المقاسات على كذا نوع من المبردات من سيارات مختلفة وكانت جميعها سيئة

Exactly as described.

Decent product.

Worked well, kinda tough to get out the really tough damage, it took a little bit of a beating and I had to rip one of the pins off the kit to keep it going
