BH Auto Foam Stripping LSP?

Using 4% as instructed in a foam pump sprayer. 40ml Auto Foam, 960ml Water. LSP is HydrO2 (2 weeks old). Left to dwell for 4-5 minutes, rinsed off well. Beading and sheeting goes away after the solution has been applied, then rinsed. HydrO2 was applied correctly to fresh panel wiped paint.

Help?

Thank you.

Either your application of HydrO2 hasn't bonded properly or it's not very good. I use BH AF in every wash and my LSP (Collinite 845) is still going strong after applying it back in October. Did you wash your car with shampoo too or just use the AF?

I’ve had a similar problem this weekend too. Had jayswax ceramic applied 2 months ago and I’ve been happy with it. Used auto foam for the first time on Saturday through a pump sprayer, 120ml with 3 litres of water (gave another car a quick once over too).

Found that pretty much all the sheeting ability from my LSP had gone. Washed my car with dodo juice BTBM straight after and when I rinsed off the water was just staying on all the panels as if it had no protection on what so ever.

Only thing I think may have affected it could be that due to it being a hot day the auto foam did look to dry on the car in some places? Was thoroughly jet washed off however. Bit disappointed as I had high hopes for it making my wash routine a lot simpler, but now it looks like i need to go reapply some LSP!

Never had this issue with any of my vehicles, mind you I use a lance to apply rather than a pump sprayer, though it should'nt make any difference really.

Nanolex Si3D is my ceramic coating.

Not something I have experienced myself so not able to give any solid advice. Can only guess it's possible it's dried to the panel or the LSP used isn't exactly the most durable.

I am sure I read somewhere before that Autofoam wasn't PH neutral. I might be mistaken I can't remember but I'm sure someone was on about it before. Regardless I still think it's a great, not my favourite but it cleans very well!

It isn't Rob but that doesn't mean it will strip wax. So many misconceptions with regards to PH levels. Can have two separate chemicals of the same PH level, one will kill you and the other is harmless. Same story when it comes to chemicals being used on LSPs.

I didn't allow the BH to dry. HydrO2 is very durable. I applied it to fresh clean prepared paint. The only pattern emerging is those with pump sprayers (with BH) have had an issue.

I tested the BH during the wash. I sprayed it onto a small section, worked it with the wash mitt, rinsed off. LSP had completely gone. If I spray the BH on, leave it to dwell, wash it off, it seems to strips more than half the LSP.

BHAF is incredibly safe and gentle on LSP, even at near neat concentrations, you're unlikely to strip an LSP to the point of naked paint.

The only way I could see serious damage being done to the LSP is if the product was left to bake on in the sun. In that instance, with no fluid suspending the active ingredients, I imagine it will harm most lsp's.

From the results of your test, I'd say you've either got a seriously bad batch of foam or for some reason there is residue being left over after the rinse that is making it look like there's no LSP. LSP is actually really hard to remove completely, even neat IPA will struggle without some rubbing and multiple applications.

I’ve used via a pressure sprayer at about 4% dilution and had no issues with it stripping my wax etc - indeed when I pressure wash off, the waters beading on the panel.

Wonder if it’s your LSP ?
