I don't think washing your own car is that good. I take it to a good car wash. But I always detail it myself. I always use meguires products. I think they are much better than mothers.
when i first got my car i bought all this shit for it. I clayed it like 2x and that made it shine like a son of a bitch....but after a couple months doing all the work got old and i take it to a 8 dollar car wash down the block.
I have the dealer do it when I have them change the oil/filter. $90 inside and out.
Car looks like new when I get it back.
They give me a free loaner to drive.
BUT not the vette. I do that with soft everything for zero scratches.
All Myers products.
a long but soft bristled wide head brush on a telescoping handle works well....if u get a system down pat washing doesn't take all that long. a 20 minute 70-80 mph blast down I-10 drys it off.
