Back in 2003, a gravel truck happen to toss some gravel on my hood....so..I was left with a some scratches:




I've since then buffed the hood....but you could still see the scratches. Also, a few hairline cracks have appeared...probably because of the lacquer primer I used. So, tomorrow is the big day, I'm going to bring it to work and give it a new paint job. I'll post pictures when I get it done!

Hey Shawn... Are you gonna strip that old lacquer primer off?

Well, I thought about it...

The painter said I wouldn't have to. He said he could seal it and paint it. I DA'd the hood, to feather some of the fisheyes out...which worked well. Then, I wetsanded the area that looked like was "cracking". It wasn't the primer....the actualy first layer of fiberglass has some small hairline cracks in it. So, I repaired them. Do you think I should strip the whole hood and restart?

Well, lacquer products are a thermoplastic which means heat and solvents can break them down...
All 2k products are thermoset...once they're hard nothing can break them down. The molecules are crosslinked.
That primer will keep moving under your thermoset clearcoat...Especially on a black car in the hot summer..Which causes shrinkage, swelling and eventually, failure.
If you repaired some areas, you may see "hotspots" under the paint where the repair is. That will be the edge of the lacquer reacting to the new product.

thanks for the heads up, I'll definently keep that in mind. You really seem to break everything down which is awesome.
