I use all Meguiars products.
I'll let you in on my secret,
Step 1 - Wash & Dry (weekly).
Wash with a warm solution of 'Meguiars NXT Generation Car Wash' using a microfiber covered sponge.
Dry car completely with a microfiber towel.
Step 2 - Surface Preparation (When required).
Application: Use an applicator pad for each separate product.
Removal: Use a microfiber towel for each separate product.
If you have what is known as fallout on your paint (run your hand across the washed paint work, if you feel little bumps, you have fallout on your paint) you can take the step of using a clay bar on the effected areas.
Don't make a habit of clay baring or use it of you do not need to as it will ware down your paint.
If you have what is known as spidering (looks like swirls in your paint in the sun) I use 'Meguiars SwirlX' or 'Meguiars Ultimate Compound'. Apply and remove the same as you would when waxing.
If you have any heavy colour fade or oxidation in your paint, you can use 'Meguiars Ultimate Compound' or 'Meguiars ColourX' to prep the paint.
Again, only do this if you paint is bad (don't make a habit of doing it) and apply and remove the same as you would when waxing.
If you have scratches, I use 'Meguiars ScratchX 2.0'.
Apply only to the effected areas. Apply and remove the same as you would when waxing.
If you need to bring a shine back into the paint, use a polish. I use 'Meguiars Ultimate Polish' over the entire paintwork of the car.
NOTE: Apply and remove to small areas at a time. If you allow it to set it is an arsehole to remove!
By this point, you want you paint to feel like glass when you run you hand across it.
Step 3 - Waxing (When required).
Application: Use an applicator pad for each separate product.
Removal: Use a microfiber towel for each separate product.
Waxing.
I use 'Meguiars NXT Generation Tech Wax 2.0 Paste' over the entire paintwork of the car.
Apply to the entire paintwork and allow to dry before removal
Then you can get into detailing the trim, wheels, interior, lights & seats etc.
On a weekly basis I do step 1 (takes about 1 hour)
I do step 1 & 3 on a 1-2 month basis (takes about 3 hours)
I only do step 2 when required (not often as steps 1-3 take about 4-5 hours to do).
Here's the results...
I'll just add, I have no connection with Meguiars, I just love my car & even more when it's shiny.
