I am hoping to start my part time detailing buisness in April and I have just a few concerns. Right now I am stocked up on pretty much everything I need to do a complete int/ext detail but there are some things I am considering, First off I do not own a compound polish, I have SIP and 106ff but I am afraid that I might come across a clients paint that needs more that the standard SIP/106 treatment. I feel that its probably neccesary to a have a compound polish in my supply cabinet in addition to SIP and 106, and if so which one, I was thinking maybe 3M extra cut or Megs possibly or anything that will help with oxidized or heavily swirled paint. Also my only vaccum is a metro vac n blo, so far I think it works fine but I have vaccumed just a few cars with it and the carpets really were not very bad. I thought about buying a 6.5hp wet/dry but im not sure if its worth it being as I already own a brand new vac n blo and later down the road(after I hopefully make some $$ I will invest in a compact hot water extractor. A pressure washer has been on my mind for a while and I cant decide if it is a useful tool that I should invest in, how important is a prssure washer when it comes to a professional detail to you guys and is it really worth the money? Also I am concerned about different paint types and single stage paint jobs. I really dont know much about how to care for different types of finishes. What type of products should I use and avoid when it comes to soft paint or single stage paint and how can I easily tell if the paint is "soft" or single stage? Lastly what do I do about clear bras? If a car has a clear bra on it do I just tape off where it ends and polish the paint as I normally would and leave the bra alone? I think about starting up this little buisness and I wonder what kind of jobs I might encounter where I might feel "unprepared". I just want to go into this thing knowing that I am well prepared and confident that I can accomplish pretty much any task within reason. For example I found that a badly soiled leather seat needs more that Z9 to remove the stains so I should look for a stronger cleaner, so obvioulsy some things are just trail and error but I dont want to be doing trial and error when I am in the middle of detailing a paying customers vehicle. I want to be as prepared as possible before I begin detailing for paying clients . From now until mid April is going to be practice, I have a few more cars lined up that im going to be working on for free, this will be my test bed. I appreciate any input/advice you guys have and any tips would be greatly appreciated also. Thanks
