the floor on the inside looks 100% but with the leg off you can see just how thin it has become.
so more work here to get it how i want it.
leg was very rusty inside

Hi Mick, out of interest, how many hours did they charge for the blasting? (just wondering how fast we work compared to others!) Looks like they use the same media as us. Most places seem to be going over to it now.

Yep, you need to prime it pretty fast. Sometimes , when the humidity is very low at the time of blasting, you can leave it for 12 months and no rust will form, other times it will start to go within 2 hours. Its down to the humidity at the time, as no seperators ever fetch all the water out of the blasting air.

This summer has been very humid. We have blasted two cars this week and have zinc phosphate primed both within a couple of hours just to make sure!

he spent 7 hours on it, could not find it cheaper around here. i even got a quote for £900.

even with me taking underseal off it was a pain to blast:) but hes done a a great job i think,

i think you would of worked out cheaper. excluding the 450 mile round trip:)

i got it home without getting it wet, and painted it 2 days after. you could just start to see a sheen of brown:) in places.

Yea 7 hours sounds fair including the setup and "unsetup" time (which takes a while).

Was talking to the big blasters' round here (Chantrells in Narborough) where I buy my glass media from, and they recounted the story of a mobile soda blasting company which a customer of theirs wished to use on a historic Porsche 911. They apparently charged £100 per hour, and in 9 hours had only done one side of the car on the outside! Needless to say the soda man went home and it got blasted with glass!

As you'll have seen from yours, the glass does a lovely job, the key left on the surface is perfect for subsequent processes.

Your car is looking very nice by the way!

Top work Mick, 1 x root free manta, almost as good as that hatch in New Zealand.

Guess opel never wanted a manta to last forever, this is one fast and efficient way of starting from stratch,

Just want to ask, what sort of protection are you adding to keep her tip top!

guess its just etched at the mo. are you going to too pack her and then stonechip?

Keep up the excellent work, its gonna be one rot free very fast Manta

started fitting the 400 rear arch today,
im fitting the rally tech kit with the fixing flange on the inside,
1st of all i offered the kit up and marked where it met the body. i also marked the fixing holes and drilled them out.
i used masking tape to mark where i was going to cut, i cutting out as high to the fixing flange as possible.c499a13a.jpg


i cut the inner arch about 2 inch back.
