VHT Clearcoat Problem Need Advise
VHT Clearcoat Problem Need Advise At first when I tinted my tails they came out amazingly smooth but I touched them a little too early and i had a few finger prints on them so of course I had to redo them. I wet sanded them down to get most of the clear coat off, vhted them some more and clear coated them some more. And now those once shiny smooth tails are now blotchy and rough...
1) What caused this to happen? Was it the clearcoat I used or the process I did?
2) What can I do to fix them? (List steps)
thanks,
Jam

you have too many layers, too thick of coats and you probably didn't let the clear cure before you sanded it? let everything dry for a few days, and then wetsand it until it's smooth and don't put clear on it this time.
You don't have to go through all of that. Just wait a couple of days, wet sand using 1500 and 2000 progressively. Just make sure that you take your time and do it really well. After that, use a PC if you have it and apply either maguiars ultimate compound or a compound made for plastics. It'll come out as shiny as the stock ones.
hmm that sounds like a good plan.. probably gonna have to throw out whatever polishing pad I use on the porter cable afterwards but that sounds like a good plan. i'll try it today and post up results
No need to use a compound just for plastics. Its car paint that you are buffing......not bare clear plastic. Treat it just like you would the paint on your car, essentially thats what it is, you are working with a clearcoat.

i used the best clear coat I could possibly use, I ordered it from online a while back ago so i don't remember the name, but it was special cause it could spray the clear coat in the same volume per second as a standard HVLP spray gun.

Not if it is underneath the clearcoat. Sanding VHT is like sanding a a candy clear coat. The more material that is on it (VHT, the darker it is). If you don't sand PERFECTLY level, it will be splotchy bc some areas have more VHT than others.
so what would you advise me to do? I'm gonna try this porter cable plastic polish method and if that doesn't work.....should I just sand it all down and start all over?
if its already uneven, i would just sand it all off now- ~400grit to take it off, and then ^600 to smooth it out. then do your VHT coats, then your clear coat. i'd recommend Dupli-color clear, i've never had any problems with it, and neither have the other people who i know of that have used it. some clear coats dont seem to work to well with the nightshade.
then once its all done, dried, and fully cured. a light wetsanding, buffing, and polishing. should look/feel like glass

I just wetsanded it w/ 1500 grit .. used m105 then m205 on the porter cable. and then used meguiars plastic polish. and it definitely did the trick. It corrected the clear coat and is a lot smoother. too bad I have no time to do the other one until next week.. i'll post up a before and after soon. Glad this is resolved.. cause I really diddn't wanna sand it all down and start all over. This can now be used as reference for those who will encounter the same VHT problems as I did.
