BMWNA advises not to use polymer sealants on new cars

I am kind of surprised that Pro Wax would say that on their web site.



It is possible that they may have information that is contrary to ours. If so, I sure would like to see the source once in for all!:confused:
 
Hotford:



I think we are talking about two different things. Modern OEM paint doesn't need to "breathe" or whatever you want to call it. However, a refinish paint job (as ShineShop put it) does need some time to fully cure. Hence, prowax products would be one of several different lines of products suitable for body-shops to use on their freshly done paint-jobs.

A refinish paint job from a body shop is a different story however as they need time to AIR CURE the paint - not bake it so it takes a while.

Another myth debunked.

Hey!

I agree with what you are saying and have the same belief as you do. But if you look at the ProWax Link I provided above, it does sound like like they are talking about automotive paints in general. You would think that for their top of the line Polymer they would advertise correctly and accurately.



Cheers!:up
 
I've been diligently researching this so-called "bulletin" and I'm lead to believe that it's a fake/hoax post.



I tried to contact BMWNA direct but didn't get any response. So, I asked for help from some fellow BMW owners over at Roadfly, and after receiving the same information from many of them, I can only conclude the bulletin is a fake.



All of the BMW owners that responded to me said the same thing- their owners manuals indicate the same info, "Protect the finish using either carnauaba or synthetic-based waxes only."



I verified this info in my owners manual and my E39 repair manual (CD's)...I'll keep trying to get an answer direct from BMWNA, but for the moment, I'm 99.999% convinced the bulletin is a fake.

The information I have from the OEMs and paint manufacturers states that heat is used to evaporate solvents quickly in refinish paint jobs and that AIR is the main factor in the curing process, not the heat.

The paint is actually hardened with use of a catalyst. It's a chemical reaction happening on your paint. Most chemical reaction rates increase with heat, so the heat helps it cure faster......
 
Quoting from my BMW Caring for your vehicle booklet that came with my roadster, “Protect the finish using carnauba or synthetic-based waxes only�. My bimmer has many coats of Zaino with no apparent problems.

All a marketing tool!! Otherwise why would other cars use synthetic waxes (like Autoglym) as a sponsor in places like the UK (including BMW).

I was just about to post that today, as I just came across that book in my owners manual also.
 
This is the same scheme they have going with Castrol, right on the oil filler cap on my M5 it has Castrol and the sticker on the engine recommends it. Castrol pays them to do that, I imagine Meguiars has some deal going with BMWNA. I use Kalsse on both my BMWs and love the results, it's just more rubish from BMWNA.
