UPP on paint

[imported_brerpie]

Hey all,



Is it ok to leave UPP on the paint for 4 hours or so before buffing off? Will this cause any harm?

I`m a newbie, so bear with me. But, odds are it won`t do any harm, but it won`t do anything to benefit you. I bet it would be more difficult to remove though.

~One man’s opinion / observations~



Bonding and Cross-Linking Process:

Adherence- the application of a thin even film of product to the paint film surface will bond by surface tension Drying- the primary catalyst is an aerobic process so sufficient drying time should be allowed. This will vary in accordance with temperature/humidity of the ambient air.

Removal- remove product residue by buffing, using a clean dry cloth and a light even pressure

Cross-link – allow sufficient time to elapse to enable cross-linking before the application of further layers or other products



There is no advantage to leaving a product on the paint film surface after its dry and without removing the residue (its what’s left on the PFS that needs to cross-link) typically it’s just a lot more difficult to remove.



Typically UPP requires >24 hours but anytime up to a 72 hour period is recommended for cross-linking and before any other products are applied.







~Hope this helps~

I`ve left P UPP on for all sorts of timeframes before removing. No problems...In fact, unlike TOGWT`s experience (equally valid, I`m not knocking his input), generally the longer *I* leave synthetics on, the easier the residue buffs off. As you can see, experiences vary, but with P UPP, four hours never made it harder for *ME* to remove. FWIW, *I* usually remove it with suede-style MF bonnets on a random orbital.
