Rattle can clear (poly)


Recommended Posts

Ok for the rattlecans enthusiasts.

Who has had luck with rattlecan poly clear coats?

How long have you needed to wait before buffing?

What grit have you wet sanded with?

What was your finally buffing step/compound?

How pleased are you with the durability of the finish and have you experienced cracking or chipping?

Currently I have 2 guitars that I am spraying and just gauging against what some of you more experienced brethren have accomplished.

Thanks for the suggestions.

Crack open a beer it's friday! I'm knockin back some Sammy's and settin up some axes. The only way to relax!

Poly is fine but expect hairline cracks at wood joints. It happened to me. Wood WILL expand and contract with temp/humidity conditions and , unfortunately, poly doesn't like to stretch. My last guitar finish looks like the bartop at your local pub. I laid it on THICK. Mostly because I didn't use grain filler on the mahogany. But once you get above that level its easy going.

I sprayed every 2nd day over a 2 hr period, 3 to 4 coats within that period. Light scuffing with 320 and a once-over with a tack rag before every spray session. Don't press too hard with the tack rag, sticky residue left behind and the poly WON'T stick. There are about 15 coats laid down. After a couple weeks I gave it a quick once-over with 320 to 400 grit to get larger blemishes, drips etc. out. If I hit wood anywhere I laid down more poly. I wetsanded with grits ranging from 600 to 2000. Don't use the coarser grits on sharp edges/corners. If you break thru to wood you got trouble. Poly is hard to patch to look uniform. Thats why its wise to lay lots down in the first place. Flat areas were sanded with a rigid block while curves etc. with a sponge block.

I hand polished with Meguiar's step 2 polish and swirl remover. Yes I'm still happy. :D

Awesome, that's just what I wanted to hear.

I heard that lacquer cracks more, so I guess a few hairline possibilities is not so bad.

I was planning on waiting amonth just to be safe for dry time, so I should be totally safe. I'll post some pics when I finish.

I used Minwax poly and had very good luck. I waited two weeks before buffing.

I sanded in increments between 1200 and 12,000 with micromesh.

Buffing was performed by ROXY finishing. So I don't know the grits used. But it had a great shine from the 12,000 grit.

Durability has been great, no problems. I put on 8 coats. The problem is with sand trough. It was very tough to retouch where I sand trough the layers.
