Plastic Renewal - Gtechniq C4

Recommended Posts

I decided to get some Gtechniq C4 Plastic Restorer to see if it could sort out the scuttle panel and make the window trims better.

 

This is the stuff

 

I got a bit carried away and forgot to photograph the before...but the first picture has a half and half. The Blue Grey is untreated, the blacker part treated.

 

Picture 2 is the same part finished that day and picture 3 is the same part the NEXT day, so it's dry now.

 

The Gtechniq is expensive, but you don't need a lot. So far I'm happy but I'll wait a couple of months before saying its the sh1t :)

I trialed this when it first came out , and tbh it was very disappointing after the time scale it boasts , it trialed it on an astra as the plastics are bad it was a monthly job so monitored it regularly , it was on the scuttle and customer let me just do half .

after a month it was gone , scuttle on the supra needs a spray to get into all the corners , I did mine with a cheap silicone sparay and its outlasted anything ive tried over the years , and quick to re do . don't waste your money on the C4

The VW crowd spend a lot of time cleaning these black plastics (as most mk1 and 2 Golfs, amongst others are covered in black plastic) and they tend to swear by the G4. That was the reason I bought it, Some Corrado owners are getting a year between applications of the door rubbing strips.

 

I guess it must depend on the material.
