Use resto ricks undercoating... I find it takes mulitple coats to look like factory, but sprays nice.

I'd use Ricks if going original. I've used the 3m stuff and didn't like. My last car I sprayed Bedliner because it's going to be a driver and I love it. This car is very much going to get driven, a lot and hard. Mind if I ask what brand bed liner materiel you used? Is it shiny or pretty dull looking ? A buddy of mine who does painting advise this very idea, and right now I'm leaning that way pretty hard I want it protected and if I can get reasonably close to the texture it has when new ,,, The cars owner and I'm good with that. I asked someone else who had use the Resto Rick stuff and sounds like he had a similar experience that I did , especially the mess part.

I'd say it's like a semi-gloss? I used Herculiner and sprayed it with an undercoating gun I'm thinking around 50 psi. You'll have to play with the psi to see what works good for you and it takes 2 good coats to cover but don't spray to thick or it will run just like anything else. Just make sure to stir it good. This Herculiner has an aggressive texture also it but I like it. Now if your looking for something with a little smoother texture and you can also add paint to it and change colors it is called Hippoliner. I sprayed my truck bed with it and this stuff is also pretty dang sweet and it's harder than a whores heart. I don't have good enough service to download the pics tonight of it.

Try dropping the air pressure down. Bill, I used 3M for some touch ups and was happy. I think I used 30-35 psi and was at 12 inchs away I always go with Resto Ricks when needed Good Look. Bob

That looks good. x2 on trying to vary the pressure.
I used UPOL Raptorliner Bedliner, very good stuff to work with and lays down very nice. Rock hard surface.

Bed liner is fine if your going to keep the car... go to sell it and it looks like its covering up stuff a lot more than undercoating. I've done it before... if the prep isn't really good, be prepared for it to fall off in chunks/crack etc. Undercoat sticks a lot better and flexes better. [quote=Silver70]I've done it a lot! There is so much wrong with this post right here it ain't funny. I scraped the factory undercoating off of my car and torched some of it off. Believe me if anything is going to hide anything it's factory undercoating and Bedliner sticks as good and will not crack and it does flex. Bedliner will show more than undercoating and you just can't gob it on and cover up $hit like your letting on.

Bedliner will show more than undercoating and you just can't gob it on and cover up $hit like your letting on. You must be using spray can bedliner if you think it's thinner than undercoat per coat. Good bedliner is like 3 times as thick if not more per coat. Like I said, you want to hide stuff, use bedliner. I've used both at least 20 times and good resto rick undercoating looks so much better. I used to think the same as you, but not after the last car, never again... it's good for a truck bed and that's it. Bedliner looks like plastic, just looks out of place on a muscle car.

To the original poster... If you're getting cob webs, then the solvent in the paint isn't all that compatible with the paint itself and/or is evaporating too quickly. Many companies have swapped out "good" solvent and replaced it with acetone (not a very good paint solvent & evaporates fast, but gets around various states' "VOC" regulations).
You can put the gun closer (less time for solvent to evaporate), turn air pressure down as others have suggested, or maybe thin the paint with a slower solvent ("summer blend" if you have that option).
Bedliners are usually either polyurethane or polyuria. Polyurethane dries slower & is more flexible. Polyurea dries in 15 seconds and is more brittle. There are also some polyurethane/polyuria hybrids out there.

Before I installed my NOS quarters years I go I sprayed some 3M inside my quarters just to save time from having to do it after I installed them. I had the same result as you. I ended up scraping everybody bit of it off.
