i agree with rider, you need the correct dilution for washing, but its kind of hard to know correct dilution with a foamer. too high of a dilution will weaken lsp's but gotta remember with foaming its not to manufacturers instructions so even if it says wont strip it can with high dilutions. now the foamer im talking about is the foam cannon not the gilmour foamaster, that thing just sprays sudsy water(IMO) with very little foam and pumps out more gpm then a pressure washer, so that one has less chance of degrading lsp's due to lower dilution. now with a pressure washer your using less water at a higher pressure so your dilution goes way higher and can degrade your lsp. so for the cannon i would use as rider said and about 1/4oz and the rest water, soaps can still foam a ton without a lot of soap so remember that... also play around with the adjustments on the top of the foam cannon as well to get a nice wash mix and just find that perfect setting for that soap. you can also not foam your car with every wash, can just do a standard wash with pressure and no foamer unless your car is loaded down with road grime, that will help with lsp's lasting longer. another option is use a good spray wax after every wash(i do this) and it really gives the car that just waxed look and that awesome slickness. i love my optimum car wax or xmt 360 spray wax...good luck!
