Layering summer wax-Megs #16 or IW845?

[smprince1]

Usually, I've applied a few layers of sealant (EX-P, UPP, etc.) to get me the best protection base through the summer. Of course, every so often the base gets a spray extender such as OCW, QD+, UGE, etc. to help make it go longer.

This year, instead of sealants I want to give the so-called durable waxes a try to see if they hold up in the summer heat.

My process would be to do a complete paint prep: wash, clay, polish to remove swirls.
Then, prior to waxing apply Clearkote VM.
Then, apply a few layers of either Megs #16 or Collinite IW845.

In your experiences, which of these waxes would have the best durability, looks, etc. Which would lend itself to applying another layer every 6-8 weeks throughout the summer? Or, a combo of the two? My vehicle is metal flake grey.

Thanks for your responses.

Why not get this best of both worlds, continue using your sealant and layer with 845IW or #16, this is usually make favorite combo. I use 476s in the winter instead of 845IW.

I use both at different times (#16 and 845IW) and find that in the Florida sun you'll get an easy 4-5 months out of 845, plus a great look - nothing seems to bother it. You would probably also like #16 but it's hard to find (no longer produced) and a little harder to apply. 845 will outlast any carnauba I've ever tried and is considered by many to be a beauty wax.

Nothing wrong with using IW or 16 as a base. To me the big difference between the two products is the ease of use with the Collinite brand over the #16. I couldn't tell the difference between the two products otherwise. Both a couple of tough waxes.

Yeah, either/or. If you feel like a paste (and can still find it) go with #16. If you feel like a semi-liquid go with the 845. If you want to smell crayons use #16, if you want to smell "detailing chemicals" use 845. 845 is easier, but #16 isn't bad as long as you apply it thin.

Thanks for the input guys.

To be more clear, I already own both #16 and IW, but I have only used the #16 to date. Usually I apply it after a sealant like EX-P or UPP.

I like the #16, but after reading so much about the '"legendary" durability of IW I thought about giving it a try this year instead of a sealant. Also, I wanted to try VM as a glaze under the LSP and I thought it would affect the bonding/durability of the sealant so I wanted to eliminate the sealant and just go with wax.

#16 and #845 are both great products, and are the two waxes that I use most often.

They are both very durable, but IMO, #845 is the durability winner by a good margin.
