I'm looking to Mod-Podge a pair of Faital.Pro 3" drivers (3FE22s in 4ohm). My intention is to use these as a wide-angle driver in a car, so I'm hoping this will improve their resilience to moisture and temperature changes. Due to their cost I intend to buy a couple of pairs, treat one pair then the other, measuring and listening as I go. The point I start making things worse I'll stop and install the other pair in the car!
Where do I start with watering down the glue and what consistency am I aiming for, how many coats and how heavy etc? Is something like the Visaton LTS 50 a safer bet for beginners? Just looking for a safe start point here so I don't trash the drivers straight away.
Thanks!

And they will sound better. They will fog up if the humidity gets really high.
Describing exactly how much to water it down is somewhat dependent on how long it has been on the shelf. Typically only a small amount of water needs be added to thin it down enuff for a FR. I have just slathered it on woofers i want to really beef up).
Best to start with too little water.
You want to put as thin a coat on as you can, too much can wipe out the topend. And it need sto be carefully applied as quickly as possible. particular care around th edustcap, some are temporaily easily damaged.
Reminds me i need to PK my 3FE22.

Do not use "glue"at all but tile/roof sealing acrylic/latex which is impervious to humidity (duh! , it´s made and sold exactly for that use), gets deep in all pores and crevices (again, it´s designed to do that), has low residual mass and stays flexible forever; while any kind of water based glue is too heavy, thick even if thinned down, rigid, varies properties with humidity, etc.
Do you have a recommended brand/supplier? I may try this on the second drivers as a comparison.
Thanks for the advice. I will try and find some sort of turntable to speed up application.
The Faitals fit perfectly in the OE mounting with 2 of the 4 mounting ears cut away, and are very easy to source here. I did look at other options (i have a pair of Jordan JX53s here which could be good), but the Faitals look very easy to fit and seem to sound pretty good.
It´s a very common water based transparent roof/tile sealant, your friendly Paint or Home Improvement shop assistant will know instantly what are you talking about.
White milky liquid, dries transparent and cone takes on a dark black hue.
Same product used to impregnate paper and cloth cone edges, but here super diluted with water.

I have some Thompsons waterseal in the garage, will check the contents of that. Also some Lithofin slate tile sealer, but that is clear, not milky. I have a latex floor primer (for tiling on concrete) too but that is a delightful shade of Kermit!
PVA sealer is white and and then goes transparent when dry - see https://trade.evo-stik.ie/product/general-purpose-pva - as an example.
In general they look whitish (not they are colour white,no pigments involved) because they are an emulsion, a suspension of tiny drops in water; when water evaporates drops stick to each other and become transparent.
But some commercial product might look transparent, no big deal.
Instead of compromising speakers (you can´t remove it once applied) get a piece of black cardboard or poster paper at some stationery shop and brush a couple patches on it,then you decide.
It really helps on a big driver, on a little one like 3FE it does not end up getting used.
