Gtechniq C4

Used this amazing product on Saturday, Having tried all the none specialist products from maguires and Autoglm with great instant looks but they just didnt last beyond a few days and there i was back to ugly grey sills again,

This product actually bonds to the plastics and changes the look permanently, Preparation is hard work as you have to clean everything to a surgical level, All previous products need to be removed and then several cleanings with Isopropyl Alcohol product only then can you apply the C4, The finish is mat and i guess is like how it left the showroom all those years ago, I did the entire car both sills the front and rear lower valences scuttle panels and the window surrounds. See how it lasts and weathers but internet reviews say its the real deal

I've had a crack with Auto Finesse Revive, a couple of weeks down the line and still looks good. Although the G4 looks the business too ?

I wonder if this would work on coloured plastic. Like the hazard switch and seat belt release buttons. I have a spare hazard I can try on the back when my bottle arrives.

It does work on the seat belt clips and hazards, this is my before and afters. They have stayed this way for about a year so far.

Looks good. What size bottle did you use for the entire car 15ml or 30ml, and how much if any did you have left after the car was finished?

i had the 15ml bottle you use it in tiny quantities and it goes a very long way, I ran out of the pads but its only ladies( or gents) make up removal pads, did the entire car and PH1 is a Big area i had one third of a bottle left over

Goodshout... the pink hazard switch has bugged me for years, enquired to the the local alfa dealer, but £65 to replace was just OTT.
Have just invested £24.90 for 15ml :ermm: and looking forward to getting to work on all those difficult plastic bits.

Just beware this is not permanent, their own marketing says 'up to 2 years' and at least one review on Amazon mentions being able to remove the layer of C4 with a pressure wash!

Yes agreed i am happy to re apply it after 2 years rather than using the other products and it lasting just days

The pressure wash removal i am guessing is where the product was applied to a dirty surface and its bonding effect was not able to happen, You honestly would not believe how many passes i made with this alcohol and more and more dirt and previous product kept on being removed, its only if you have a perfectly clean surface can this product work

Did you just clean the surface with alcohol and then apply the C4 or did you need to do anything else?

I was doing the pre cleaning for some time..................... my sills had had all sorts of attempts at making them stay black so my cleaning process was long and time consuming, once i had what i thought was all old treatments removed i then went onto the Alcohol with a lint free cloth, was a long hard process, But having had it on there since this thread started it is still like it is in these pics, obviously it gets dirty with use but cleans up back to the matt black it was at the showroom

I did all the glass surrounds since as they get blemished with polishes and the results are excellent

Brad many thanks... next question; how do you get the driver's side scuttle panel off? I managed to remove the passenger side, give it a good clean with detergent and have started using alcohol on it but the driver's side has got me stumped. I undid the nut on the wiper expecting it to pull off but it wouldn't budge. Am I missing something or does it just need brute force to get the wiper off?

If you have a look at the side you can get of you can see the type pf connectors you are dealing with, In all honesty i had no issue just removed the wiper arms and removed them quite easy, There are no bolts or screw apart from what you can see so once wiper arm and hex screws are off it should just lift with a little force

Bend the wiper arm, you know like you do to clean the blades, higher you can bend it up the better, do that and kinda wiggle the arm on the spindle.

Thanks for all the help... a bit of brute force and an FBH got the wipers off. Scrubbed and cleaned the scuttle panel once off, cleaned out underneath and treated... looking good now.
