This was not easy to find so my numbers may not be exact.
Lift is ph12 out of the bottle and mixed 1:10 has a ph of about 10. Most good coatings will handle a ph of 10 but a ph of 10 will not clean as well of a ph12.
Bilt Hamber talks alot about Panel impact ratios (PIR) because if you mix 1:10 and then you use in a foam cannon it becomes further diluted when applying bacause a foam cannon/gun mixes it with water.
Lift at 1:10 then shot out of a foam cannon is from ph7 (ph neutral) to about ph8.5. Again from internet I have not tested. I believe this to be why most Lift reviews aren’t good
If you watch video’s or do research most foam cannons will have a 50/50 mix (or more) of Product to water in reservoir. This to get the ph to 12 when it “impacts panel”. This is alot more than were use to using.
The “PIR” is a formula to factor in additional water. If your interested on PIR I pulled this of internets.
Calculating PIR (Panel Impact Ratio) for Foam Lance use - YouTube
The simple way around this and why I recommended a IK foam 12 to [mention]Klasse Act [/mention] is if you use a pump sprayer you only have to figure PIR for what’s in reservoir as your not diluting it through cannon.
To get 4% which will give you a ph of 12 of BHAF you only need to mix 4oz to 100oz of water.
You have to calculate because different pressure washers and cannons will affect pir.
After telling you all this to be fully transparent i’ve never figured PIR for my set up and just bought a foam pro 12.
And to actually answer your statement. Due to a low alkaline PH lift isn’t hurting your coating or at least not noticeably.
You also are getting better results than something like Griots Surface wash (my fave ph neutral one) but no where the results of a BH pre wash at proper PH level.
Sorry just confused myself

. Hoped this helps you or someone in future.
