Meguiars M105 & Meguiars Ultimate Compound

[Theostoubos]

Are these two the same product ?

No, 105 has more cut. UC is the consumer version that has less cut and is easier to work with. Both are good and have their place.

Thanks.

Does UC contain any fillers ?

[Mike@DedicatedPerfection]

UC does not have any fillers

[embolism]

no fillers but does leave behind polishing oils that can mask remaining defects if not removed.

sometimes UC can finish lsp ready. It's good practice to clean the residual oils for the reason mentioned above or if you are using a sealant that requires a clean surface to bond to the paint.

It's not as critical for waxes but we're all about overkill here at AG...

IMO both are very similar with 105 has a bit more aggressiveness in the correction process.

would you use UC for a brand new car to create produstion swirls and imperfections? anything better?

assume not a one week old paint job, but a fully cured job like a BMW or Benz......made overseas...

I'd say in that case both of those products would be overkill for a new paint job. Remember to always use the least aggressive approach possible. If you want to stick to using the Meguiars line, i'd try scratch X first since its less aggressive than ultimate compound.

.. or even swirl X

Try M205 first. If that doesn't work, try UC. Even though both are compounds, M105 still has noticeably more cut than UC.
