D151 vs m105

I have a 2005 red dodge neon srt-4. It has some light to moderate swirls that I would love to get rid of along with some other smaller imperfections such as bug marks and etchings(bugs didn't eat down through the paint, mainly surface damage). I will be applying the product by hand and I was wondering which would be better, d151 or m105. I posted several months ago about the bug marks on my front bumper and a few had recommended the m105. If there is something that would be better, feel free to recommend it. My plan is to wash> clay> "polish" with d151 or m105> wax. How much pressure should I use when applying the d151 or m105? Are either of these considered a polish? If not, please recommend a good polish I should use. Also, feel free to correct the detailing regime that I listed above if it is incorrect.



Thanks for your time :up
 
Without having your car in front of me and doing a test section, neither I nor anyone else can give you a 100% goof proof answer.



Honestly, if you are going to work by hand, just fill the swirls and wax. Meguiars #9 and NXT would work just fine.
 
ScratchX is meant for spot polishing, #9 is meant for straight vehicle polishing and would be more economical to use.



If you simply wiped ScratchX on and off and expected results, that isn't how it works. You have to work it in to get results.
 
I used SwirlX and ultimate compound by hand with a micro fiber applicator. The car had light to moderate swirling and I was able to get the paint to maybe 80% correction with a tone of elbow grease. It looks a ton better but you can still see them in the sun. With red it may work a little better I used it on dark blue.
 
M105 works great by hand, just be aware that it is an aggressive compound. Majority of the time it finishes really well and you dont have to follow up with a less aggressive finish polish.



Megs Ultimate Compound is the consumer version of 105 and just as good but is less aggressive.



Like Scott said, you can just rub it on like a wax and wiped it off it will not work, and will probably look worse than it did. You have to work it a little with a little passion to work it in. Then remove and check results and re-aaply if necessary. You dont want the compound/polish to dry, wipe it off while still a little wet.



I have used M105 and UC by hand and machine (PC 7424) and they work great. Have not used the D151 but ordered some and it should be here today so hoping to try it out this weekend.



Good Luck with what you are doing.
 
Like Scott said, without doing a test spot its hard to say. You could however do your own test spot, taping off a 20x20 section and trying both products, taking notes on your pressure, your work time by hand, how many times you overlapped, and that should give you an idea of what you will have to do with the rest of the vehicle. It will be alot of work, but in the end it will pay off big time. I'm sure you know, but if at all possible check your work in the sun...if not the sun a good LED light will work well, or if you can get your hands on one, a Brinkmann Dual Xenon is killer!! Have fun, take lots of Ibuprofen, LOL.
 
When I mentioned ScratchX earlier, I meant to say SwirlX. I have used ScratchX for spot treatments on a couple of things and it worked great. I wasn't too thrilled with SwirlX. I did put a good pit of elbow grease into it, and it helped a little, but not to the extent that I would have liked. So if I go with m105 or UC, what would I need to follow op with? I'm thinking a polish and a wax but I'm a noob when it comes to more "involved" detailing.
 
as far as abrasiveness within the products, using M105 or UC first, I would follow up with the swirl-x with not as much pressure, that should leave you LSP ready.
 
Whatever you finally settle on, don't make the mistake that others have made and did their whole car before checking, only to find out how horrendous it looks now.



Test on a small spot. Maybe a portion of the trunk lid. Once it looks good, check it in the sun. If you now have your technique down, then and only then, proceed on to the rest of the car



Just be aware that polishing a whole car by hand is tiresome and a long process. I get tired when just polishing a small scratch by hand, I'd never want to do a whole car without a machine.
