Topic: VHT paint?

[Vinhead1957]

I have only tried the Caliper paint but found that it chips easily.  I baked it the second time with the same result. Should I have used a primer for aluminum?

I always used VHT without primer on aluminum and had very good results.
I painted my caliper with the VHT gloss and it's holding up very well.

Proper prep is the key, thoroughly degrease before painting. I use acetone. (everything was glass-beaded prior to painting as well.)
I have never baked VHT. I usually just apply three not-too-heavy coats about 10-15 mins apart and let dry for 24hrs.

I didn't wipe it down with acetone but it was very clean before paint

Residue from cleaning solutions and the oils from hand prints, while virtually invisible, are enough to retard adhesion of your paint.   Sand it back down, clean and degrease it properly, handle the piece with clean gloves, and then do several light coats, allowing just the flash time (from the can instructions) between coats, and then let dry for a couple of days.

And YES, the proper primer will help adhesion....

Use VHT primer if you do.
The reason I went without primer was because I had issues using VHT over both Krylon and Duplicolor primer.

I recently bought VHT gloss black caliper paint and VHT cast aluminium caliper paint. They recomend that you as a primer use SP118 hightemp primer - http://www.vhtpaint.com/products/flameproof/

I hope that will workout great !
