make sure to put in new motor mounts Roger sells em get the volvo mounts, before you put in the engine also do the OPG.

Nicole the flaws are where on the PU cover where it has seen damage and the substrate ( under lying coating) has cracked to the PU surface, even sanding this down to flat will result in the crack reappearing when the fresh top coats are applied,
then after the paint cures the cracks will resurface and the hairline cracks will become visible.
the only way to remove them is to start with a fresh surface and build it back up. with the correct flex agents added to the primers and paint,
BTDT too many times.

If I want to just have a repaint of the car, what is the best method to remove / prep the car for new paint?
If I use a paint stripper than do I have to do both sides of the panel and also then paint both sides?
I do not want to do the jambs etc, just the exterior panels that are dull and showing age and don't want to remove all the panels?
What I am envisioning is that the front windshield has to come out, the rear quarter glass has to come out, the sunroof, front and rear bumpers, rub strips, door gaskets and rubber moldings and that should be it to get a good sanding and shoot new paint. The rear hatch glass can remain, just remove the molding. Do you guys feel anything I have overlooked?

PU cover? I am racking my brain for PU.

Hi Bilal928S4, paint stripper is definately the way to go if you are going to do a bare metal respray, not only does it save time and arguably $$$, but there is much less chance of warping the aluminium panels by using sanding discs.. Having said that, the main reasons we are removing the paint on this car is because a) its cactus, and b) I`m changing the colour.. And as any paint guy will tell you, theres nothing as good as painting bare metal..
However, you could strip the paint with paint stripper and do a closed door respray, or you could do what we did on my 82 and flatten the existing paint back if its in good nick and put another coat over the top. On the 82 I had some clear coat lifting, it wasnt enough to warrant stripping the paint back to bare metal, and frankly, its an everyday car so I didnt want it to be off the road for that long.. the 2 pack finish is strong, its been done properly, and it looks superb and should stay that way for many years. Also, modern 2 packs have a different "look" to the original paint, they look much thicker and a lot more vibrant.. some like it, some dont.

Not much progress in the last couple of weeks, just slowly stripping out the engine bay. You can see the damage on the front left side of the car. Its had a high hit and was poorly repaired. The front is out by 10mm. Luckily the rails are fine and the damage is easily repaired. Once the engine bay is stripped the front suspension will come off and we can repair the fropnt and give it a coat of paint.

I know these pictures are a bit boring at the moment but I enjoy reading these threads and seeing a car progress.. some of the threads on here are a real inspiration.. especially in those dark moments when you think "why!!"
