Cellulose High build / Etch???

[div6926]

Hi,

I will be starting to take my Mg Midget back to bare metal over the next few weeks as this seems to be the best option due to the amount welded repairs and new panels fitted.

I will be using Cellulose from Jawel paints but I'm not sure if I will need to use an Etch primer prior to the coats of High build primer? I spoke to Jawel about this and they recommended i use a 2k activator to mix with the primer, I'm not keen on this as I will not be using an air-fed mask.

Also, what sort of timeframe do i need from stripping the old paint to filling, blocking and the first coat of primer before surface rust appears, is it days or weeks?

Thanks,
Dave.

you need etch only on the bare steel

should paint asap really , kinda depends how damp the work area is

Etch primer and high build primer is a 2 step process which you can replace with special 2K epoxy primer and paint on with celluloses. The epoxy is the glue so you may need a primer that you can sand like celluloses does so brilliantly. All possible with new paint technology, this is reality so it seems. A note on the respirator mask. It has tightened straps that give streams on your skin, are uncomfortable as such, and if they don't fit too well, you can smell the paint!

all 2k high build primers need a activator.for your car if i was doing the job ,i would put one good coat of epoxy primer on which has a activator.Let dry then ,three to four coats of high build.if the car is going to be in bare metal .Clean the metal down with panel wipe ,Then put a good coat of epoxy on .That way your metal will be protected as and when you do the panel work.You can filler over epoxy ,as Jaguar recommend it.
