7. The paint striper of claim 5 wherein said trigger mechanism is a squeeze trigger whereby a user may apply a squeezing force to said squeeze trigger to alter the actuation of said spray.

8. The paint striper of claim 5 wherein said trigger mechanism is a lever trigger,

whereby a user may apply a force to the lever trigger to alter the actuation of said spray.

17. The paint striper of claim 1 wherein the nozzle is a beveled block nozzle comprising:

a) a nozzle block,

b) a beveled face, and

c) a spray tube receptor,

wherein said spray tube receptor is of sufficient size and shape to receive a spray tube of the container, and

wherein said beveled face is formed in said nozzle block and said spray tube receptor is formed inside said nozzle block,

whereby a force applied to said beveled face from the axle will deflect said nozzle and apply a actuating force on said spay tube.

18. The paint striper of claim 17 wherein the nozzle further comprising a notch to fit said axle is a means of locking said nozzle in place when said nozzle is in a first position relative to said axle where said notch is fitted over said axle, and

whereby said axle is a means for actuating said spray when said nozzle is in a second position where said axle is not aligned with said notch.

19. The paint striper of claim 18, wherein said notch is rectangular.

6. A paint striper comprising:

a) a container holder of sufficient size and shape to hold a container,

b) a spray nozzle to be connected to the container,

c) a means for actuating a spray,

d) a wheel, and

e) an axle,

wherein said container holder is connected to said means for actuating said spray,

wherein said axle passes through and connects said wheel to said container holder,

wherein said trigger mechanism is a shifter and said means for conveying force is a cable,

whereby a user may apply a rotational force to said shifter to actuate said spray.

9. A paint striper comprising:

a) a container holder of sufficient size and shape to hold a container,

b) a spray nozzle to be connected to the container,

c) a means for actuating a spray,

d) a shortened container holder, and

e) an extension, comprising;

i) first shaft,

ii) a second shaft, and

iii) a three way connector

f) a third shaft,

g) a fourth shaft,

h) a first wheel,

i) an axle,

j) a rear wheel, and

k) a second axle,

wherein said connector holder is connected to a means for actuating said spray,

wherein said extension is connected to said shortened container holder, and said shortened container holder mounts to said extension,

wherein said first shaft and said second shaft are connected by said three way connector, and

wherein said three way connector connects to said third shaft,

wherein said axle passes through and connects said first wheel, said container holder, and said fourth shaft,

wherein said second axle passes through and connects said rear wheel, said third shaft, and said fourth shaft,

whereby said paint striper will apply said spray to a surface.

10. The paint striper of claim 9 further comprising

1) a second wheel

wherein said axle passes through and connects to said second wheel.

11. The paint striper of claim 10 further comprising

m) a fourth wheel, and

n) a fifth shaft

wherein said fifth shaft runs parallel to said fourth shaft and connects to said axle, and,

wherein said second axle passes through and connects said fourth wheel and said fifth shaft.

12. The paint striper of claim 9 further comprising

a) a plurality of pads,

wherein said pads are attached to said container holder,

whereby said pads keep said container in place.

13. A paint striper for applying a spray to a surface comprising:

a) a chassis comprising;

i) a container holder of sufficient size and shape to hold a container,

ii) a plurality of shafts,

iii) at least one connector, said connector having at least two receiving ends for connecting at an angle at least two of said shafts,

b) at least one wheel,

c) at least one axle,

d) a spray nozzle to be connected to the container,

wherein said plurality of shafts are connected to said connector, and

wherein said plurality of shafts are connected to said container holder, and

wherein said chassis is connected to said axle, and

wherein said axle is connected to said wheel,

whereby said paint striper carries said container in a path over said surface.

14. The paint striper of claim 13 further comprising an actuator for actuating a spray comprising a sheet of material having a receptor of sufficient size and shape to receive a spray nozzle, whereby said spray is actuated when said nozzle receives a deflecting force through said actuator,

wherein the spray nozzle comprises a spray tube receptor,

wherein said spray tube receptor is of sufficient size and shape to receive a spray tube of said container, and

wherein said spray nozzle is connected to said actuator,

whereby said spray nozzle actuates a spray when a force is applied to said spray nozzle by said actuator.

15. The system of claim 14 wherein said nozzle is a shaped nozzle,
