Hi Craig, just after some advice from you… I want to rep-spray my 83 e30 bmw with acrylic lacquer. The original paint (acrylic I think), is in ok condition so I am going to sand back the shine for keying of the new paint. I am after a pretty nice, flat, showy finish. I am adding a fibreglass bodykit which I have already sanded back with 400. The front fibreglass bumper I have taken back to the gelcoat. The bonnet has minor stone chips/rust in the stonechip dents.
Should I spray on an isolator or etch primer first at all for adhesion of the new paint?
Should I just sand the stonechips and tiny dings with rustspots back to metal, use a rust neutraliser, then use filler and then hi-fill primer over the top?
For the bumper should I apply a flex agent after the first prime?
After everything is hi-fill primed I will wet sand, then repeat so I have 3 coats of hi-fill primer.
This will be followed by 3-4 coats of colour with wet sanding of 1200 in between coats.
No wet sand following the final colour coat.
Two to three coats of clear with wet sanding of 2000 in between.
Then buff and polish afterwards.
Would this be a suitable process? I havnt sprayed a car before. Ive read Pat Ganahl’s book, but he mainly concentrates on 2pack which I dont want to use for safety and novice reasons.
Cheers, Travis

Hi Bernard,
I can’t say that I have come across the problem you are having with your paint, although I have heard of things like humidity blisters and thinners entrapment that I believe can cause this type of thing. I did find this troubleshooting guide which might be of use – http://www.sherwin-automotive.com/~/media/Sherwin-Williams-Files/Files/Reference/Trouble%20Shooting%20Guide/tsg.ashx

Hope that helps!
Regards,
Craig

Very Helpful site, Having a go at re spraying my Restored BJ40 Landcruiser myself and your site has helped me to no end, I had no idea and was sceptical about doing it my self, but im have a go and it is coming up great, real personal satisfaction and a total cost of about $ 400.00 for everything including Full undercoat and Acrylic paint,

Thanks again

Im now looking for my next landcruiser to have a go at

[...] can pressure. Dry cans well before spraying!! There's a very good car/spray painting guide here – http://autofix.com.au/blog/how-to-re-paint-a-car And you'll find three coats is pretty much par for the course with spray – it can be even more [...]
