After reading about the different experiences in durability that people have encountered,it reminded me of a frustrating experience that i had 3 years ago while using Duragloss #601/#105 on three Nissan vehicles.I applied #601/#105 to two Nissan March/Micra cars,one Metallic Blue,the other b/c Red.The other car was a Nissan Qashqai in Metallic orange/Red.I used the same step saver mix on all three cars,and all three were polished and wiped down with Eraser before applying the #601/`105 mix.Application and removal was easy as it`s always been with these products,and all three cars looked great.
About a week later it rained,and that`s when i noticed that both March/Micra cars had very poor beading,looked just like a dead LSP,whilst the Qashqai had perfect tight beading and fast water run off, as i had always seen with these products.All three cars had original paint,the Qashqai had Hard clear,the Metallic Blue March/Micra was pretty soft(swirls/scratches removed with PO85rd on a polishing pad via DA) and the b/c Red March/Micra was medium to hard.To cut a long story short,out of frustration and not being able to come up with an answer as to why there was such a huge difference between the water behavior while using the same product on three different cars,i re did both March/Micras,however the results were exactly the same,i even tried a new bottle of each product in case i may have got a bad bottle,same thing,tried hand and machine application,tried letting the product dry longer,tried applying the #601 to the car separately and then following with #105,same thing,tried just #105 on it`s own,same,tried #501,then #105,same thing.To this day,i can duplicate the same results on these cars using these products,the results are always the same,it`s as if the clear on both March/Micras is rejecting the products.It`s something that has always bothered me,as i have no explanation for it,never been able to figure out why.I think it really must be as Accumulator has always said,YMMV.
