Re: ONR and Collinite 845
Collinite after ONR will be fine. As I've mentioned on other threads, ONR (at least v2, I haven't used v3 yet) used on 845 had a strange effect for me - completely no slickness on the paint, though it was still beading ok. Other people on various threads and forums have posted similar experiences. Didn't have this issue with DP Rinseless.
Also, about two weeks ago, experienced a similar issue with 915 and ONR, though worse this time - the 915 beading was visibly degraded, particularly for a two-week old application.
