Any suggestions/ help prepping car for paint

[Wolvesboy]

Hi All,
When I bought my car the clear coat was badly damaged down the passenger side and on the bonnet. I carefully scraped the damaged clear coat off and then rubbed the edge down so the "lip" is smooth. However, the line is now white in most places as it was the only way of getting the edge smooth. For any paint guys out there - do I now have to prime coat the car before applying base coat again or do I need to use a special primer for the glass fibre material?
these photos are pre plasti-dip which worked very well indeed but I may need to paint the car properly!

needs further sanding so the edge is feathered and not such a sharp line ...and yes prime and block sand before painting

Awesome, thanks for the confirmation.

infact i think i would try and sand most of that back to the original /sound paint job ...prime the front end , blend into the doors

If this is something you have never attempted, and judging by the lack of sanding the rest of the front, you should probably give it to someone who does, that needs blending into the doors.

Pits, no need to be so curt buddy. This was just prepped for the plasti - dip as stated in the original post. The clear does not need to be sanded for plasti - dip and it actually worked really well. However, I am now thinking of painting it properly.
My initial question was concerning the glass fibre body and whether I needed to do anything extra before the new primer? I am assuming that If I do not sand past the original primer then all should be ok?

correct , if priming onto old paint /primer , it wont know the difference what the panel is made of

id suggest epoxy primer

Can I ask if you plastidipped it yourself what did you use to spray it and how many litres did you use?

Not sure why it has come out like that I am sure I put more into the reply.

Really you will need to epoxy and bake it, well I personally would, however you can just scotch into panels so there is nothing shiny left, prime, base, clear, but this is much more of a job than you think, even blending would require a lot of skill because of the door recess at the hinges, so ideally doors need to come off, seeing as there is a considerable amount of "failed" paint, I genuinely think you are better off getting it done professionally, there is so much more to think of, extraction, how are you going to bake it to cure it? A space heater wont work as it releases too much moisture into the area and will land in the paint, which will ultimately fail.

However if you feel confident enough to do it, then I would certainly give it a go, make sure you have some decent lighting from all angles so you can see any parts that aren't flatted down properly etc.

I did an E39 many years back, I used about 5 litres but that was thinned, I forget what I thinned it with these days and ratio, but I would say 5 litres would comfortably do a Chim
