Do you have to polish after you use a clay bar?

Hey guys. I've had my car for about 8 months now and this will be my first time clay barring and waxing my m3. I was wondering since I have a MW and no swirl marks show, do I need to polish after I use the clay bar or can I just skip polishing and wax it? Sorry for the noob questions I'm new to this. Thanks for the help!

You don't *have* to. Use a mild clay bar and lots of lubricant and you'll be on. Even if there was some mild marring you probably wouldn't see it on MW

No you don't. I used clay lube with claying and then dried with micro fiber towels. A nice coat of wax is a nice finisher to protect the finish. I do this 2x a year minimum with great results.

You don't have to polish afterwards but clay bars will mar the surface. You may not see or notice it but it is there. Depending on how fine a grade the clay is, you may have to do an intensive polish or just a one-step wax.

Do you wash it again right after you wax the car or just go right to waxing right alway?

And that's a full wash with soap and water or just a rinse?

You will need a full wash with soap and water. Using the clay bar with lubricant will leave lubricant residue and all the dirty stuff you clayed off on the car.

Usually if I clay, I'll polish, but not too long ago I clayed a few sections then followed with klasse and some wax. The next day, I did notice some extra marring from the clay.

I use the dark blue clay from detailedimage which is listed as "fine." Granted, I was rather aggressive with the clay, and I have lemans so marring is more likely to show.

Washing after claying is safer, but using plenty of quick detailer and wiping down well is usually enough

The clay is slightly abrasive, so to get the most gloss back into the paint, it's a good idea to use a fine polish afterwards.

Was told never to use dawn to wash car by a top detailer.

IMO its fine for this type of use. Ideal soap to use when you want to strip off everything before waxing/sealing. When I am doing a full detail I actually use the dawn soap as lube for the clay and wash/clay/wash almost in one step (making sure to fully wash off any abrasive contaminants after each step). May not be the best lubricant but I am compounding afterwards so no worries there.

Obvious downside to using it all the time is it will strip any wax/sealant and perhaps may be hard on the plastic/rubber pieces on the car in the long run? Its definitely not going to hurt the clear coat, you would wash that with acetone if you wanted to.

Only when you want to strip off existing wax. Otherwise don't use it

I always instruct my clients to polish after claying a car, using a light polish or a paint cleaner will take care of any marring introduced by the claying process as well as increase the gloss on your vehicle and since you have a MW I would suggest you to go with a paint sealant instead of just a wax (paint sealant will give you 6-9 months of protections unlike a wax that you'll get 2-3 months) Consider this sealants - Blackfire Wet Diamond, Wolfgang Deep Gloss, Sonax Polymer Net Shield.

-Just my professional opinion
