So I've been using UC/SwirlX and my bottles are just about empty. DI had a sale going on, so I decided on stepping up to m105/205. My question is, what kind of difference can I expect from UC/SwirlX? From lurking on here, it seems like m105 has a short work time, and can be a little finicky and prone to drying? Some also have said that M205 has a fair amount of oils in it and IPA wipedowns are near mandatory? Other than that is there anything I should know? My first car is going to be a newer (mid 2000s) F-350 that needs some serious correction on the passenger side. After that, I will be doing an '03 Toyota 4Runner that again needs a fair amount of correction. Thanks for any advice. I really hope the work time is as short as people have said it is, that is one of my chief complaints about UC.
