Foam sprays are messy unless you have a steady hand, Gel can be shilacky and leaves a sticky residue on the tyres which will build up and Liquid shines are the easiest to apply
I don't recommend the
meguiars gel.
Here are my methods
1.
Meguiars Pro Vinyl Protectant & Valvoline Syn Power Shine
Spray the
meguiars on a cloth and some to the tires. Then buff off and spray the aerosol valvoline over the top for a dry, non sling wet look finish
2. Jal Chemicals Tyre Rejuvinator
Apply the liquid to a cloth and outside edge of tyre. Apply in one big motion clockwise over the tire and buff
Give rejuvinator product time to cure and slowly absorb into the rubber, thus bringing back the suppleness and dark black color to the tyres
3. Car Chem Seal It
Spray Liquid tyre rejuvinator directly onto tires, remove excess from wheel. Do not buff
Allow a couple hours at least to absorb. If you drive the car very shortly after shining the tyres, the shine won't last the trip to your destination.
With both Seal It and Jal, the more time you give it to absorb, the darker and wetter the finish
best results obtained after 6 - 24 hours. Will last at least a week even in rain if allowed this much time
