M80/83 Combo

[Spectre32]

Ok, well I am trying out some product and I have tired M105/205 before on my tailgate and it didnt work out so well. My tailgate has been repainted so I decided to give the old standby a try. I washed the truck and then taped everything off. I am using a Meguiars DA with the soft buff 2.0 Pads. I applied the M83 first with a polishing pad. I did it twice over the whole tail gate and it removed a majoirty of the scratches and other marks. I switched to a finishing pad and applied one coat of M80 and then a coat of Yellow Wax. As it stands right now it looks way better but i still have scratches and what not. As for my technique I used speed 5 for thr 83 with a medium pressure and then for the 80 I used a speed of 2.5 and very light pressure. So my question is.. do I need to step up to a more aggressive product or do I need to get the rotary out and use the same process but just the rotary with M83?

Re: M80/83 Combo

M105 is quite a bit more aggressive than M83, but it is also formulated a lot differently, and needs to be used in a different manner. If the scratches are too deep, you will not be able to remove them with a rotary and a more agressive compound. Perhaps you can give M105 another shot after you read up on how to properly use it.

Re: M80/83 Combo

Well I had a thread awhile ago and it appeared that no matter what I did, I was unable to get M105/205 to work on my tailgate. I tired it on the bedsides and had great results. So it was brought to me attention that 83/80 was a tired and true combo. It yeilded better results using my method above an M105/205 did.

If you are experienced with a rotary polisher, why not give that a try with M83 and M81? Both products were originally formulated to be used with rotary polishers, and rotary polishers are far more effective at removing scratches than DA polishers. Follow up the M83 with M81 if you need to remove any micromarring.

I do question your technique with M80, though. Even with a finishing pad, I would still use speed 4 to 5. Speed 2 or 3 is fine for applying waxes or pure polishes, but M80 is a cleaner/polish, and its diminishing abrasives need to be broken down.

Re: M80/83 Combo

There is a great step that falls between M83 and M105 that works great on a D/A and offers plenty of cut. It's called Ultimate Compound. Don't be fooled by the fact that it's a $9 consumer product you can pick up at Pep Boys, Advance Auto, etc - it's derived from M105 but is far more forgiving on a D/A. Give that a shot before jumping up to a rotary.

For the record, the difference in result you're seeing with M105 on this repainted panel versus the rest of the vehicle is a classic example of how different paint systems can react very differently to the same input.

Re: M80/83 Combo

Thanks for the input guys. I'll grab a bottle of UC and try it out. I'll also apply some of the techiquies prescribed via the post from AL. I have some experiance witht he DA but hardly any with the rotary.
