Where does MDR fall in a coating prep workflow?

[paulgyro]

I have a black BMW with water spots I'm preping to coat.

What should my workflow look like?

I'm guessing the following.

1) Pre-soak

2) Wash

3) Iron remover

4) Clay 

5) MDR?

6) Polish

7) Panel Prep

8 ) Coat

your work flow looks right - you can use iron remover (at least FerreX) as your clay lube.  I would rinse the MDR before polishing.

Bit late, but I personally would swap MDR and Claying. Reasoning: Get all your chemical decontamination done before you (optionally) start mechanical decontamination, which will cause marring. I would implement loooooong dwell times, then claying will hopefully be obsolete. Use a strong pressure washer as well, that helps.

There's a video on Opti-Coat's YouTube channel, called "Winter gets the decon" which is a good process to follow.

Awesome thanks! I checked out the video and what you say makes sense.

Heijneker, I did as you suggested and used MDR prior to claying (even though there were no water spot) and it made it so I didn't have to clay!

Nice! Great to hear it has worked that way, awesome. Thanks for giving the update. How did you use the MDR?

I used a foam applicator with MDR, applied to the paint, let it sit for a 2-3 minutes, washed off. Did the bag test and found no contamination. 

I tried a similar approach on my hood because of contamination, the hood being coated with CarPro CQuartz, leaving the MDR on for about 20 mins as I couldn't get the contaminated to leave.  I washed the hood to remove the MDR and found the coating to be DEAD.  I was shocked to see this. Have you heard of this before?  I thought MDR even with long dwell times was coating friendly.

[Ron@Optimum]

MDR is coating friendly - Optimum's coatings - we don't test or make promises on other brands. 

I like chemical decontamination, feel clay is over used.  Combinations of Power Clean, FerreX, and MDR can be used to decontaminate paint without clay. 

[Heijneker]

Well there's your answer, sorry to hear the coating is gone. But time for something better I suppose 😉. Shows the power of MDR, love that stuff

Yeah same here Ron, of course a bit more time consuming than mitt Claying with Ferrex after Super Clean, but I think this can give a better clean, and pretty much ensures a clean sheet.

But claying is okay if you're polishing anyway I guess, and there's no coating on the car.

Per Yvan before if you use a light / fine clay like the Optimum clay towel it doesn't mar so no need to worry about polishing.

Ron, would a MDR dwell time of say 20 mins hurt Glosscoat?  

[paulgyro]

Sorry for all the posts, I found out why MDR killed my coating, CQuartz has a ph resistance scale of 3-11.  

MDR has a ph of 2.65

[Ron@Optimum]

was going to add the coating may not be gone, may just be muted.  Different cleaners can reduce Gloss-Coat when over used - I don't believe MDR dwelling for 20 minutes + strips the coating but wouldn't be surprised at it effects durability (same is true for Power Clean, FerreX, etc - use reasonably and rinse thoroughly).

Been watching the maintenance videos for Opti Coat+ from various sites and while helpful there seems to be some confusion. 

One site uses  ONR/Power Clean/Ferrex/MDR/Hyperseal in that order,  while the Optimum channel used Power Clean/Ferrex/MDR/ONR (didn't mention sealer) in that order.

I'm puzzled why ONR would be used before Power Clean, given Power Clean appears to be a more powerful remover of road grime, etc.

Would the Power Clean/Ferrex/MDR/ONR/Opti Seal be best approach for new Opti-Coat+ finishes,  switching to Hyperseal after Opti-Coat+ has fully cured ?
