Hey guys I have a question...
Ive been pondering about my box and amp rack in my car and the black vinyl. Im kind of getting tired of it and want a flashier look.
My car is black and I want to have an auto finish paint on the mdf. I was thinking if i do it like fiberglass.
1. Filler and sand, say 100, 200, 300
2. primer and sand 600-800
3. 3 or 4 light coats of black (sanded with 800 between coats)
4. 2 or 3 coats of clearcoat/sealer (wet sanded with 1000 between coats)
5. wet sand with 1500 then 2000grit
6. finish with rubbing compound, polish, and wax.
ive done soem body work before but i never painted mdf. am i missing anything or any step i should not do on mdf?

MDF absorbs paint like a sponge. So you will probably want to use a few coats of epoxy based material to fill (filler) the pores first. Once the pores are well sealed, then sanding them to a fine finish would be good. Then a few coats of primer, paint, then clear coat as mentioned.
The epoxy coating will be your base coats and seal the wood well. Then build up your finish as noted. May not need much of a filler unless you get a poor surface after pulling the vinyl off. Depending on the glue used, a little acetone should take off the residue. A little heat (hair dryer or heat gun) on the vinyl, will help release the glue.
Any other comments out there guys?

PS You may want to get some non-skid rubber feet for the box as well. Keep it from sliding around in the truck...
PSS May I suggest that you try a test piece before you go all out on the rack and box... this will give you a good feel for what you have to deal with and make your mistakes on the test piece.... not the final product.

I was thinking of some body filler the kind that has the consistency of cake icing with some glue in it or a simple spray can of Kilz™ Sealant would work too. yeh the vinyl came off pretty easy (im doing the rack first) I used the thicker marine vinyl.
I should be taking pictures shouldnt I? hehe

Kilz II is a great product as is a PVA based primer. A few coats of same will be a good preface to new finish... but these are more for drywall and home painting projects. Kilz original is oil based, KilzII is water (layex) based.
It might work... but you'll have to do some expirementation to see if this will work adequately. The body filler will help (bondo or epoxy) to give you a hard finish. A lot of sanding may be needed with this step... but dondo and epoxies are very durable and a hard finish too.
Yes, do take pics and document your process so we all can learn from your experience!
Good luck,
