Does anyone have any experience with high build primer? The paint on my hood is highly oxidized so there are little pits and scratches all over, but it's only in the paint. I sanded 60-100-120-220 and I can still see the pits and ect. I really don't want to bondo the entire hood, not do I have any desire to sand down to metal. Could I simply roll a high-build automotive primer over the well-sanded paint and expect it to fill these minor imperfections?
