My experience shows that if something can be screwed up, it will be screwed
up.... I dislike telling a well meaning customer that his attempts to
service his neighbours/aunts/grandpas/girlfriends car have made recovery
difficult and the bill is $X00.00 please.....
There's not much you're going to do to a car that can be considered
inexpensive, these days.... having a badly handled mistake is not going to
make things cheaper.
Cheap tools can render a fastener difficult... after that, the vise grips
come out - maybe a pipe wrench or any other cobbled idea. By the time
someone with experience gets to it.........
Any decent tech is worth his money.... if someone makes his job harder, the
costs will be passed on down the line.
