BFWD and condensation post application

**Gurge** · 07-12-2012, 01:56 PM

finally got around to polishing my truck this year (been busy with clients) and saturday morning post polish I applied 1 coat of BFWD. it was hot and sunny all day so this coat had plenty of time to cure so I know that is fine

last night after work I washed the truck and applied a 2nd coat of sealant and buffed off after 730pm

couple hours later after dark I noticed condensation all over my truck. I don`t know if this was the sealant `sweating` as I`ve seen this in the past with 845 and I was the only car with condensation on the paint.

Regarless, it was wet. and it was wet from dew upon morning inspection.

From what I understand with some other sealants out there, this type of exposure is bad for the sealant. as in the sealant loses some durability. However, there are sealants like KSG that you can dilute with water on application or buff off with the assistance of water based products (QD)

Can anyone comment on how sensitive blackfire sealant is to the situation I described?

The truck looks great so thats not really up for debate. just curious on the behavior of the sealant in various conditions such as what happened here. Thanks...

BLACKFIRE Wet Diamond will not sweat so what you have noticed is condensation. The majority of BFWD cures fairly quickly, the rest of the time is waiting for the remaining amount to catch up. So even if the exposure to surface humidity would effect the uncured polymers, the amount would be negligible. If you want to apply another coat just to be sure then you can.

I`ll second Todd`s comment.

I`m not sure where the phenomenon of sealants or waxes sweating comes from.

If you think about it logically, for this to happen the layer of protection which is no more then 1/10 of a micron thick somehow would need to carry its own supply of moisture in order to sweat.

The small beads or droplets of water some see comes from airborne moisture settling on the freshly sealed or waxed surface.

Wax has a very low surface tension and conversely water has a very high surface tension. If enough moisture settles on a freshly sealed or waxed surface beads of water will begin to form appearing as sweat however body panels do not sweat....my opinion of course...

good info. thanks. sounds like since it was the second coat and it had over an hour to cure before I saw any condensation that its fine.

I have a client later today that will be getting LSP applied around the same time of day. good to know I can stick with BFWD if necessary

Now I can worry about more important stuff like what to top the sealant with on my truck. Its a silver tacoma so midnight sun is probably a waste. may do p21s concours paste

Midnight Sun made my silver paint look like it glowed. Try it.

Yeah if it was the second coat you are more than fine!!!

P21S has always been a favorite of mine on lighter color cars (and the 100% is just awesome on anything!
